to achieve prompt finality in competition results, and in consideration of
the numerous benefits to them, all participants, including competitors and
officials, expressly agree that:
1. They are familiar with the SCCA® National Solo® Rules and agree to
abide by them;
2. Determinations by SCCA® officials are non-litigable;
3. They will not initiate or maintain litigation of any kind against SCCA® or
anyone acting in behalf of SCCA® to reverse or modify such determinations, or to seek to recover damages or other relief allegedly incurred or
required as a result of such determination;
4. If a participant initiates or maintains litigation in violation of this provision, that participant agrees to reimburse SCCA® for all costs of such
litigation, including travel expenses and attorney fees.

INTRODUCTORY SECTION
I.1 SOLO® EVENTS
I.1.1 Definition
A Solo® Event is any event (where an event is considered to be an
entire program of competitions) in which one automobile at a time is
timed over a clearly defined course, with elapsed time and appropriate
penalties for course deviations being the determining factor for awards.
This shall not preclude the running of more than one car at a time, provided they are separated on course by adequate time and distance to
eliminate any possibility of a passing situation.
I.1.2 Revision of the Solo® Rules
The SCCA® may revise these rules or issue supplements to them at
any time, via Tech Bulletins in the official SCCA® publication and/or on
the official SCCA® website (www.scca.com). All supplements will have
a published effective date.
If circumstances create a situation where a rule clarification or change
is found necessary to be implemented immediately, the SCCA® Board
of Directors may issue a memorandum stating the change and its effective date. These memorandums will be posted on the SCCA® website
and published in the official SCCA® publication.
I.1.3 Replacement of the Solo® Rules
Effective on January 1 of each year, all previous editions of the Solo®
Rules will be superseded by the current edition. No revisions previously
published in the official SCCA® publication or on the official SCCA®
website (www.scca.com) will remain in effect unless included in the new
edition of the Solo® Rules.
I.1.4 Solo® Event
A Solo® Event is a non-speed driving skill contest such as, but not limited to, autocrosses and slaloms. These events are run on short courses
that emphasize the driver’s ability and the car’s handling and agility.
Competition licenses are not required and hazards to spectators, participants, and property do not exceed those encountered in normal, legal
highway driving. All Solo® events must be sanctioned by the SCCA®,
Inc. The Solo® Rules are mandatory for use in SCCA® Solo® National
Tour and National Championship events and standards set forth in the
Solo® Rules must be adhered to by all SCCA® Regions who organize,
sponsor, co-sponsor, or sanction a Solo® Event.
While the right to protest in proper cases is undoubted, it should be remembered that Solo® events are sporting events to be conducted in a
sporting spirit, that all events are organized and managed by amateurs
who cheerfully give their time and do their best, that the competitor may
expect some imperfections of the organizers and of his fellow competitors, and that, to a reasonable extent, these things are part of the
chances he takes in entering the competition.

I.2 SOLO® EVENTS BOARD
I.2.1 Appointment
The SCCA® Board of Directors (BOD) shall annually appoint the
SCCA® Solo® Events Board (SEB). Current appointees are listed on
the SCCA® website (www.scca.com), published in the current edition
of the SCCA® Directory, published in an early current-year issue of the
official SCCA® publication, and available from the SCCA® National Office.
I.2.2 Duties
A. The SEB submits to the SCCA® BOD recommended rules and standards for the conduct of SCCA® Solo® Events. The SEB monitors
the execution of these approved rules and standards for SCCA®sanctioned Solo® Events and maintains liaison with the Solo®
Events Stewards.
B. The monitoring of these rules includes the issuing of clarifications regarding them. Requests for clarification or advance determination of
legality must be accompanied by sufficient information to adequately
describe the situation. The supporting documentation may include
photographs, drawings, and/or excerpts from manufacturer service
manuals/documents, parts catalogs, or similar information. A minimum of six weeks must be allowed. The requestor has the burden of
adequately and accurately describing each situation and the desired
action. Members are cautioned that rulings based upon information
provided are not irrevocable if new information becomes available or
if the underlying rules are subsequently changed. Send requests to
the address on the forward page of the Solo® Rules.
C. National Championship
1. The SEB will annually make an on-site inspection of the Solo®
National Championship courses prior to giving final approval. The
purpose of this inspection shall be to ensure a safe event, to assure protection of spectators and property, to verify the use of appropriate courses, and the suitability of the program (including the
event supplementary regulations).
2. The SEB shall appoint the respective Chief Stewards, Chairmen
of the Protest Committees, approve Solo® Safety Stewards, and
other Chiefs of Specialties such as Timing, Tech, Impound, and
Course for the Solo® National Championship events. Any SEB
member in attendance at the Solo® National Championship may
serve on the Appeals Committee.
I.2.3 Core Values
The decisions of the SEB are based upon three core values that together equate with member value. These core values are as follows:
1. Increased participation and involvement.

K. Serve as a resource to the SEB to share and propagate best practices as developed and performed by regions within the Division.
I.4 SOLO® SAFETY STEWARD PROGRAM
I.4.1 Scope
The Solo® Safety Steward (SSS) program is designed to provide reasonable precautions with regard to safety at all SCCA® Solo® Events.
The SSS program is governed by this section and the SSS Guidebook
(see Appendix E).
I.4.2 Duties
The primary duties of the Solo® Safety Steward (SSS) shall concern
the safety of participants and non-participants. This includes course
security, which is defined as maintaining control over non-participant
access to the course. Course layout relative to driver and worker safety
is also a concern of the SSS. The SSS is responsible to their Divisional
Solo® Safety Steward (DSSS) as follows:
A. Serve as an SCCA® representative on inspection of any Solo® site.
B. Serve as SSS at all Solo® events, with prime responsibility and
vested authority to ensure all necessary safety precautions are taken with respect to spectator, worker, and driver (i.e., course layout)
safety. Control over course design extends only to such issues as
on-course or near-course hazards and not to design philosophy.
In SCCA® Solo® events, safety issues are those such as listed in
Solo® Rules Sections 2.1 and 2.2.
C. Verify that the certificate of insurance is correct and present at the
event site. This should be done either by visual inspection of the certificate or by telephone confirmation with SCCA® Risk Management.
If certificate is not available, call: 1-800-770-9994.
D. In the event of an accident/incident during an event, notify all SCCA®
officials and the insurance carrier of SCCA® as indicated in the Appendix E.XI.F and the Accident/Incident Report Form. A preliminary
report shall be mailed within seven days and a more complete report
mailed within a reasonable time thereafter. The SSS shall respond
to all questions from SCCA® officials assigned to investigate the
accident/incident. However, no discussion on the accident shall be
carried on with outside parties (except law enforcement authorities)
without authorization by SCCA®. In any discussion, only statement
of fact, rather than opinion, should be offered. Mail all completed
reports to the appropriate SCCA® and/or insurance carrier offices.
E. It is the responsibility of every SSS to file a report concerning the
conduct of an event with the SCCA® National Office Solo® Department if such conduct is substandard to the safety rules referenced in
the Solo® Rules.
I.4.3 Administration
The Regional Executive (RE) of the Region or his/her designated representative shall appoint the SSS for Regional Solo® events. He/she
must be qualified to officiate at each event appointed and the SCCA®
National Office Solo® Department shall be notified of such appointment
at the time of the insurance application. Changes to the appointment
can be made prior to the event by notifying the SCCA® Solo® Department, or in emergencies, the next business day after the event. The
DSSS will advise the SCCA® Solo® Department of all new SSS in his/
her division so that licenses can be issued and the National list maintained.
The SSS may appoint a substitute SSS to act as the SSS during times
that the regular SSS is competing. The substitute must hold the same
or higher grade of SSS license.
The SSS may appoint a Deputy SSS if the course design cannot be
visually observed by one person. The SSS shall use discretion in making these appointments. A list of all of those appointed shall be included
with the post-event summary.
It is suggested that where Deputies are used, a radio network separate
from that used for driver safety be used; but that the SSS have contact
with the driver safety network as well.
The SSS shall appoint assistants for the purpose of on-the-job training at each event. This assistant may serve as a Deputy SSS when
required.
In the event of a breach in course security, which might endanger any
spectators, workers, or drivers (i.e., course layout), the SSS has the
authority to stop the event until the breach is remedied.
I.5 SOLO® SAFETY COMMITTEE
I.5.1 Membership
The Solo® Safety Committee (SSC) will consist of six SCCA® members
plus a Chairman appointed annually by the SEB, subject to approval of

one qualified SSS.
F. Shall maintain a record of all SSS appointed to Regional Events and
upon notification of such appointment, verify proper license grade.
G. Shall report to the SEB on the compliance with safety rules at Solo®
Events. Shall make recommendations concerning possible action toward a region or an SSS for failure to adhere to or implement safety
rules contained within the Solo® Rules or Solo® Safety Publication.
I.7 CO-SANCTIONED/CO-SPONSORED EVENTS
The prohibition against co-sanctioning and/or co-sponsoring events by
SCCA® shall not prevent cooperation by SCCA® Regions with other
organizations provided that the events are controlled by the sanctioning Region and are conducted in accordance with SCCA® rules and
regulations pertaining to the event.
I.8 SITE SAFETY PLAN
It is strongly recommended that each Region develop and implement
an event site safety plan. Upon request, the SCCA® National Office
Solo® Department can assist a Region in developing a plan by providing a sample of the plan used for the National Solo® Championship. If
a Regional plan is developed, it should be submitted to the DSSS for
review prior to implementation.
I.9 ENFORCEMENT BY THE SCCA®
A. All SCCA® Solo® Events shall be subject to an unannounced inspection by a DSS, a member of the SSC, an SSS, an SEB Member,
or the SCCA® National Office Solo® Department who will evaluate
the compliance of the event with the mandatory provisions of the
SCCA® Solo® Rules. They have the authority to bring rule infractions to the attention of the Event Chairman for corrective action and
will file a written report with the SCCA® Solo® Department noting
whether or not corrective action was taken.
B. Regions which solely or jointly organize, conduct, sanction, or otherwise cooperate in the organizing of a Solo® Event that does not
comply with these Rules shall be subject to the following, as determined by the SEB. A hearing before one or more members of the
Board designated for the purpose by the Chairman will be granted
at a Region’s request before the measures proposed are made final.
1. Warning: During the period of which the Region must submit Solo®
courses to the DSS, to other officials designated by the Board, for
prior approval; and will be subject to unannounced inspection by
the Solo® Steward or Board Member, SCCA® Risk Management
Department, or designee.
2. Suspension: During the period of which the Region may not be
involved, in any way, in the organizing of Solo® Events.
C. In addition to the foregoing, the Region is also subject to such other
penalty as may be imposed by the Board of Directors.
I.10 INSURANCE REQUIREMENTS
I.10.1 Event Insurance Requirements
All SCCA®-sanctioned events must be insured for Event Liability and
Participant Accident coverage by the SCCA® Event Insurance Plan.
Coverage details can be found in the current copy of the SCCA® Insurance Handbook or by contacting the SCCA® Risk Management Department. The Event Chairman shall not let the event begin until assured
by the receipt of an appropriate insurance certificate that the insurance
requirements have been met and the certificate is posted at the event.
If a certificate is not available, call the following number immediately:
1-800-770-9994.
I.10.2 Insurance Application Procedures
The Event Chairman must submit an SCCA® Sanction Application/
Master Insurance Plan Request Form at least 14 days prior to the
event. Each Request Form must designate a SSS.
SOLO® RULES
1. SOLO® EVENTS
1.1 MANDATORY PROVISIONS
Sections 1 (except 1.5), 2.0, 2.1, 2.2, 2.4, 2.5, 2.6, 3.1, 3.3 (except

underlined herein. At events where kart classes (KM, JA, JB, JC) are
offered, Sections 2.7 and 2.8 are mandatory. Vehicle classifications are
not mandatory. Regions should use classing structures which are best
for the development of their programs. However, Regions may not allow
faster karts per age group than those already described in Section 19.
National vehicle classifications are located in Appendix A of these rules.
Suggested optional classes and rules are located in Appendixes A, G,
and H. The entire SCCA® Solo® Rules are mandatory for SCCA® National Solo® Events. Additional rules governing the SCCA® ProSolo®
National Series are in Section 20.
1.2 GENERAL DEFINITIONS
1.2.1 Solo® Event
A Solo® Event is an automobile competition in which one car at a time
negotiates a prescribed course, with finishing position based on the
time required to complete the course plus any penalties incurred. Where
course conditions permit, more than one car may be on course at a time
if they are separated by adequate time and distance. A Solo® Event is a
non-speed driving skill contest such as, but not limited to, autocrosses
and slaloms. These events are run on short courses that emphasize car
handling and agility rather than speed or power. Competition licenses
are not required and hazards to spectators, participants, and property
do not exceed those encountered in normal, legal highway driving. All
Solo® Events must be SCCA® sanctioned.
1.2.2 Autocross
An autocross is an event generally held on a paved, flat surface, wherein
the course typically consists of straight sections and connecting turns or
corners, generally resembling a miniaturized road course. The course
layout should be such as to emphasize car handling, driver skill, and
maneuverability rather than performance. The course is generally well
enough defined so that memory is not required to remain on course.
1.2.3 Slalom
Slalom typically refers to an event similar to an autocross, though the
term may also refer to one particular serpentine portion of an autocross
layout.
Section 1 — 23
1.2.4 Entrant
An entrant is a person who has completed the necessary requirements
to enter the event.
1.2.5 Competitor
A competitor is a driver who has started at least one run at an event.
1.2.6 SD
SD is the acronym for the Solo® Department at the SCCA® National
office.
1.2.7 National Solo® Event
A. Solo® National Championship – The event at which the Solo®
National Champion for each class is determined. Managed by the
SCCA® Solo® Department and administered by SCCA® member
officials.
B. Solo® National Tour – A collection of National-level Solo® events
run at various locations across the country as preparatory events
for the National Championship. Primarily planned and administered
as a partnership between the local SCCA® Region and the SCCA®
Solo® Department.
C. ProSolo® National Championship – Solo® National level events run
at various locations across the country using a mirror image course
format that incorporates a drag race type start system, including the
use of “Christmas tree” starting lights. Organized and managed by
the SCCA® Solo® Department with the assistance of a host Region
or club.
1.2.8 Inter-Regional Solo® Event
An Inter-Regional Solo® Event is primarily planned and administered
by a DSS using the broad policy guidelines of the SEB with assistance
from the SCCA® Solo National Office.

GCR is the acronym for the Club Racing General Competition Rules
including the associated specification books.
1.3 EVENT OPERATING RULES
1.3.1 Insurance Requirements (Refer to Section 4.14)
1.3.2 Other Operating Requirements
A. All persons in an event car must have an SCCA® membership, either full or weekend.
B. All competitors, except those in Formula Junior classes, must have
a valid driver’s license.
C. Competitors are required to wear seat belts (except Kart drivers) and
helmets when driving in competition. Roll bars are recommended.

In general, a passenger should be either a student riding with an
instructor or an instructor riding with a student during an instructional
run (as in a Solo® drivers’ school). However, it should also be noted
that some Regions allow passengers in order to acquaint newcomers with the sport. As long as the passenger meets all of the above
requirements, he/she would be allowed at Regional events where a
passenger is permitted. The only passengers who may be allowed
during competitions runs in National Solo® events are non-competitors whose role is to fulfill the state-mandated requirements for a
driver who has a restricted driver’s license requiring a passenger.
E. All cars shall be subject to a strict safety inspection based on the
Solo® Rules.
F. Basic rules and standards for conduct of events must be drawn up
before an event is run and be available to all competitors.
G. Penalties for course deviations or course marker displacement shall
be posted and available to all competitors.
H. Car classifications to be used and distribution of awards shall be
established prior to the event and available to all competitors.
I. An event chief official must be appointed to supervise the running of
the event. His duties should generally be those of the Chief Steward
of a race event.
J. All participants, including competitors, workers, crew, and guests,
must sign the SCCA® waiver form. Credentials must be issued to
and displayed by those who have signed waivers. Any competitor
found to have driven the course in any vehicle before signing the

chairman to be under the influence of alcohol or narcotics shall be
disqualified.
L. Unsportsmanlike Conduct. Any driver who drives unsafely at/near the
event location or displays unsportsmanlike conduct shall be disqualified.
M. Pressurized gas and air bottles with a pressure in excess of 200 psi
(1380 kPa) must have a protective structure around the gauge and
valve assembly.
N. It is strongly recommended for emergency purposes, a public telephone or a cellular telephone be available at the event site or at a
known nearby location.
Section 1 — 25
O. Children under twelve (12) years of age and pets shall be prohibited
in the staging, grid, start/finish, and course areas. Drivers from eight
(8) to twelve (12) years of age who are participating in an approved
Junior Driver program under the requirements of Section 19.2 are
exempt from this prohibition during their run group. Otherwise, they,
too, are prohibited from these areas. Furthermore, staging, grid,
start, finish, and course workers should be at least sixteen (16) years
of age. Drivers from eight (8) to sixteen (16) years of age should be
assigned to other worker duties as outlined in Section 19.
P. Smoking is not permitted in grid or staging areas.
Q. Cars may not be off the ground, in gear, while running for tire shaving, tire cleaning, or other reasons. EXCEPTION: Vehicles which
have snowmobile-derived drivetrains, such as Formula 500/440,
may be started with the rear wheels off the ground. If a car with
a snowmobile-derived train is started with the rear wheels on the
ground, a driver must be on board. NOTE: Karts may be serviced
or have the engine running while on a kart stand without a driver on
board.
R. In any areas of the event site designated for refueling of vehicles
there will be at least one 10-lb minimum Class B fire extinguisher to
be available in the event of a fire during refueling.
S. Course workers must be standing at all times when any competition
cars are on-course during the event.
T. Cell phones and video or still cameras are not permitted at course
worker positions or other locations within the course area. Exceptions may be granted for media relations purposes by the SSS. Permission for a photographer may be given only if the location is acceptable to the SSS and if the photographer is accompanied by a
spotter to warn of approaching vehicles.
U. Competitors are responsible for using proper support (e.g., jack
stands) to safely support a raised vehicle if any person is underneath
that vehicle.
1.4 SANCTION PROCEDURES
1.4.1 Regional
Formal SCCA® sanction is required for all Regional Solo® events.
Sanction requirements and all documents will be issued by the SCCA®
National Solo® Department.
1.4.2 National Solo® Event
Sanction will be issued by the SCCA® National Solo® Department and
the event must be listed in the official SCCA® calendar as published
in the official SCCA® publication and/or on the SCCA® web site (www.
scca.com).
1.4.3 National Championship
A. Formal SCCA® sanction is required for the Solo® National Championship. A sanction number and document will be issued only when
all requirements listed below have been met and the application approved.
B. The event must be listed on the official SCCA® calendar as published in the official SCCA® publication and/or on the official SCCA®
website. It shall include in the name of the event the following as a
minimum: “SCCA® Solo® National Championship”.
C. The course and supplementary regulations must be inspected and
approved by the SEB.
1.5 SUPPLEMENTARY REGULATIONS
Supplementary regulations will be consistent with the SCCA® Solo®
Rules and define the ground rules of competition for a specific event.
They are recommended, but not required, for Regional events. They
shall contain the following information, as applicable:
A. The name, location, date(s), nature, and classification of the proposed event.
B. An announcement, conspicuously placed, reading “Held under the
SCCA® Solo® Rules.”
C. A complete description of the proposed event.
D. Schedules and locations of all activities, inspections, meetings, and
competitions. If a separate event program is prepared, these items
may be included there, rather than in the supplementary regulations.
E. The name and address of the person to whom the entry is to be sent,
the closing date for the receipt of entries, when entries will be accepted, and amount of entry fee.
F. The manner of determining results.
G. Hours during the day(s) when official scales will be available for
competitors to check their vehicle weights.
H. All information necessary for the proper conduct of the event.
No changes shall be made to the Supplementary Regulations, except
for the schedule, after registration opens or unless the SEB (at the
SCCA® Solo® National Championship Event) or the Solo® Event Operations Manager (at National Tour events) so decides for reasons of
safety or forces beyond their control.
2. COURSE
Solo® courses should be open enough to allow good competition between larger and smaller cars, and should not emphasize high speed,
power-to-weight ratio, extreme maneuverability, memory, or visual acuity. Regional, National Tour, and National Championship events shall be
conducted on a paved surface.
2.1 COMMON SENSE AND SOLO® COURSES
Although Solo® events are non-speed events under the Solo® Rules
of the SCCA®, speed alone is not the operative factor in determining
Section 1 — 27
what is and is not a proper Solo® event. Hazard is the operative word;
hazards must not exceed those encountered in legal highway travel.
Generally, maximum speeds in the mid 50s to low 60s (mph) are contemplated for Stock, Street Touring, and Street Prepared category vehicles, and WITH LIMITED EXCEPTIONS AS DESCRIBED IN SECTION 2.2, MUST BE OBSERVED, since these are speeds with which
the average driver is familiar from everyday road driving. But it is quite
possible to set up a course on which speeds do not exceed 45 mph,
but which is more hazardous than another course on which 65 mph is
attainable.
The same sort of reasoning must be applied to cornering speeds. If, for
example, there are two identical 30 mph turns, one bordered by a 50 ft
drop off or a solid row of trees and the other by 50 ft of flat, obstacle-free
asphalt, the hazards involved are much different. The former is clearly
not permissible in an SCCA® Solo® event and the latter clearly is.
Each event chairman is cautioned to remember that entrants and workers must be SCCA® members in Solo® events or they are NOT covered
by catastrophic insurance. Furthermore, by definition a Solo® event is
open to a total novice in any car that can pass safety inspection and
courses must take this into consideration.
It would be possible to set extremely strict and rigid limits on Solo®
events regarding speed and/or course dimensions. However, it is not
the intent of these rules to outlaw event sites which cannot accommodate a course of certain stated dimensions or create the impression
that, so long as some magic speed limit is not exceeded, these rules
are adhered to.
Basically, Solo® event speeds are limited to what is “reasonable and
prudent for the conditions encountered,” SUBJECT TO THE CONSTRAINT THAT TOP SPEEDS BE WITHIN AN ALLOWABLE RANGE
AS DESCRIBED IN SECTION 2.2. Laying out a course to comply with
the safety requirements of these rules calls for the exercise of prudent
good judgment and common sense. Failure to do so may subject an
SCCA® Region to severe sanctions.
2.2 COURSE SAFETY AND LAYOUT RULES
Courses must comply with Section 1 of these Rules which is mandatory
of all SCCA® Regions. The following set of course safety and layout
rules is also required for all Solo® events. WHEN THIS SECTION IS
FOLLOWED, COMPLIANCE WITH SECTION 2.1 IS AUTOMATIC.
When laying out a course, the size of the vehicles competing should
be taken in consideration and the dimensions specified in the following
rules are only minimums:
A. Courses must be tight enough so that cars run the entire course
in their lower gears. Speeds on straight stretches should not normally exceed the low 60s (mph) for the fastest Stock, Street Touring, and Street Prepared category cars. The fastest portions of the
course shall be those most remote from spectators and property.
Turns should not normally allow speeds in excess of 45 mph in unprepared cars. It must be remembered that sites themselves vary
and not all sites will safely support the speeds shown in these guidelines (see Section 1.3). Conformity to these speed guidelines does
not preclude reasonable and prudent consideration of the conditions
encountered.
Guidelines To Corner Speeds Based On The Radius Of A Turn
The table is a guideline for Regional Officials and Course Designers; it shows values of cornering speeds versus corner radius (not
diameter) for various lateral accelerations. This data should be
considered in light of other calculations which estimate that a fast
Stock or Street Prepared car can pull well in excess of 1.0Gs in
lateral acceleration, and can accelerate from 30mph to 70mph in
less than 300 feet.
B. The course as laid out shall be on a paved surface which contains
no dangerous holes, loose gravel, gratings, oily spots, or other hazardous features. Surface features (dips, crowns, etc.) which could
cause a car to become airborne shall be avoided.
C. The course boundary shall not normally pass closer than 25 ft from
solid objects.
D. The Solo® Safety Steward (SSS) shall have the authority to disapprove a course or site for karts only, when there are upright solid objects (e.g., light poles, fence posts, etc) on the site within 50 ft of the
actual course. This does not include curbs. While safety systems for
karts provide acceptable driver protection for most incidents, upright
solid objects present potential hazard for which kart safety systems
are not well suited. This rule gives the SSS the option of excluding
karts without having to declare the site unsafe for everyone. It is up
to the judgment of the SSS whether the course design, surface, solid
objects, and type of karts running present an unsafe mix. In most
cases, the situation can be resolved by a course design change.

Section 2 — 29
E. Special caution should be applied where negative-cambered turns
are used.
F. A long straight (over 150 ft) should not terminate in an extremely
sharp turn (e.g., a short radius U-turn).
G. Except on permanent circuits such as kart tracks, the inner and outer
limits of turns and corners should be marked by course markers;
displacement of which results in time penalties. Corner limits must
never be marked by curbs, buildings, poles, trees, soft shoulders or
other hazards likely to cause damage to a car or likely to cause a car
to overturn.
H. Cars on the course simultaneously shall not run in close proximity
to each other.
I. All portions of the course shall be visible to at least one course marshal who can communicate through signals or by electronic means
with the starting line.
J. Extreme care shall be taken in the location of the start, finish, staging, and timing areas. The timers and staging area must be placed
well clear of the course in a safe area. The finish section and course
exit should be clearly and carefully defined to safely restrict speeds.
It is not recommended that competing cars be required to come to a
complete stop immediately following the finish line. It is preferred that
cars be required to slow to a walking speed within a controlled area
before returning to the grid or paddock areas. A complete stop should
be required only when unusual site conditions exist. In all cases, a
sufficient distance past the finish line must be available to safely slow
or halt any competing car from the highest possible speed attainable
at the finish without locking brakes or wild maneuvering. It is recommended that an official be assigned to control the finish area. Particular care must be exercised in the finish area to keep it free from
hazard to participants and non-participants.
K. Entrance and exit lanes shall enter the course at separate points,
though they may be close together. They will be kept clear for use by
competing cars at all times.
L. Portions of the course where significant braking is necessary shall
not terminate at a point where participants, non-participants, or obstacles are directly in front at a distance closer than that required to
bring a car to a halt even with brake problems, a stuck throttle, etc.
M. Participants and non-participants must be kept at a safe distance
from the course, particularly at the outside of turns and at the start
and finish lines. Unless protected by substantial barriers, non-participant areas must be roped off. The Solo® Safety Steward shall have
the authority to set minimum viewing distances from the course but
such minimum viewing distances may not be less than 75 ft from
the course edge in unprotected areas (areas without adequate barrier protection such as concrete or tire walls). A Region may request
a waiver of this minimum distance requirement from its Divisional
Solo® Safety Steward.
N. Appropriate fire extinguishers, flags, and material for cleaning up
fluid spills must be provided by the host Region.
O. Any Solo® event where Formula Junior (FJ) uses the same course
layout as all other classes: For any heat in which FJ is in competition,
no car in the grid may be in motion when any FJ kart is moving under
its own power. From the start of FJ competition, when the first driver
in the class leaves the grid for the start line until the last driver has
returned his kart to the FJ grid, this rule shall apply.
2.3 COURSE DESIGN RULES
A. All corners shall be negotiable without reversing by any car classified
by make/model in the Solo® Rules.
B. The course shall be at least 15 feet wide and single-file slalom markers shall be at least 45 feet apart. Any series of three (3) or more
course markers which are generally in a line and have the effect of
a slalom are considered to be a slalom. Additional course markers
associated with the slalom markers to form gates, “boxes,” etc, do
not cancel this limit.
C. A Solo® event, other than a gimmick event in which time is not the
only consideration, shall be a test of driving skill, not memory.
D. The course shall be well marked with pylons or other “markers.” The
base of each marker shall be outlined to permit accurate replacement if displaced.
E. Cars should leave a gate/turn headed generally in the direction of
the next gate/turn.
2.4 EVENTS AT RACE FACILITIES
Solo® events planned for commercial race facilities, or a private facility that could reasonably be construed to be similar in concept to a
commercial race facility, must have approval from the current Divisional
Solo® Safety Steward (DSSS). If in doubt, contact your DSSS.
2.5 SPECTATOR SOLO® EVENTS
A spectator Solo® event is one that encourages the general public to
come and watch the event, without signing the SCCA® release and
waiver form, through wording on flyers or other media such as newspaper advertisements or radio. Events where admission is charged
are also automatically considered spectator events. A Region should
exercise care in how both it and its sponsors advertise an event if it
does not apply for spectator event sanction and insurance. Spectator
events, their site controls, layout, course, and safety measures must be
specifically pre-approved by the Chairman of the Solo® Safety Committee (SSC) and an additional insurance premium paid. Spectator events
must employ site and course control barriers.
Section 2 — 31
2.6 NON-SPECTATOR SOLO® EVENTS – ADVERTISING
A. Solo® events may be advertised to the general public for the purpose of informing them of the activities of the SCCA® if the provisions of this section are met.
B. Advertising must be targeted to encourage the public to discover the
SCCA® and its activities. Examples of acceptable language include,
“Car buffs are invited to experience the SCCA®” and “Motorsports
enthusiasts are invited to come see what the SCCA® is all about.”
The focus of the advertising must be recruitment of possible future
participants.
C. Advertising must not be broad based or entertainment oriented. Examples of unacceptable language would include, “Spectators welcome,” “Spectators free,” and “Come see the excitement – slides,
spins, screeching tires!” (entertainment example).
D. All advertising must include a statement on waiver signing such as,
“Everyone entering the event site must sign a release & waiver form.”
E. When an event is advertised in the manner above, a plan must be
in place to limit access to the event site to those who have signed
the release & waiver form and to issue a credential (wristband, etc)
to those having signed the form. This may be done by either limiting physical access to controlled locations or by assigning multiple
workers equipped with forms and credentials to continually survey
the event site for non-credentialed people.
F. It is highly recommended that a minimum of two (2) Solo® Safety
Stewards (SSS) be assigned to the event.
G. Sanction application must be received by the SCCA® National Solo
Department a minimum of 21 days prior to the event and must indicate that the event is a non-spectator advertised event.
2.7 KART SOLO® EVENTS
Solo® events which will have karts competing must so designate on
the sanction application. Prior approval is not required. The rules for
organizing and conducting a Solo® event with karts are found in Appendix G.
2.8 JUNIOR DRIVER PROGRAM
The Formula Junior (FJ) program is provided that allows regions to permit minors up to 18 years of age to compete in Solo® events in nonshifter-based racing karts. The purpose of this program is to serve as a
tool for membership recruitment and retention by providing competition
opportunities for the entire family. The rules for organizing and conducting a Junior Driver program are in Section 19, Appendix G, and Appendix H. As this program is still in the developmental phase, rule updates
or clarifications may appear periodically in Fastrack News of the official
SCCA® publication and/or the SCCA® website (www.scca.com).
3. VEHICLES
3.1 ELIGIBLE VEHICLES
A Solo® event is open to any vehicle that can pass safety inspection,
has the minimum bodywork specified by these Rules, and is properly
muffled, except that vehicles with wheelbases exceeding 116” may be
excluded by the Event Chairman if he determines, at his discretion, that
they cannot readily negotiate the course. This decision shall be made
in advance if possible and included in the advance publicity and supplementary regulations. Cars need not be licensed or licensable for road
use, so long as they otherwise comply with the SCCA® Solo® Rules.
Models and option packages designated as being of a model year later
than the current year are not eligible to compete in National Tour or
Solo® National Championships, unless they have been specifically
classed by the SEB. A newly-classed model or option package is not
eligible for the current year’s Solo® National Championships unless its
listing was published no later than the July issue of the official SCCA®
publication.
Unstable vehicles with a high center of gravity and a narrow track, including SUVs, minivans, and 4WD pickups, must be excluded. Examples of such vehicles are listed in Appendix A. Extra caution should be
exercised with non-traditional vehicles (e.g., trucks using racing slicks).
Rollover Potential Guidelines
The SSC has reviewed the allowance of competing cars with higher
roll centers and has prepared the following chart to be used as a
guideline for assisting Regional members in determining whether
a vehicle has a higher than average potential to roll over in Solo®
competition. Vehicles falling into the acceptance range still have the
probability to roll over but they are less likely to roll over than those
that are not in the acceptable range are.
One method of assessing rollover resistance, and one level more
sophisticated than the Static Stability Factor (SSF), is using “stability margin”. This idea is that the vehicle’s steady cornering g-level at
which incipient rollover would occur (two wheel lift or 2WL) should
exceed the steady cornering g-level provided by the tires (maximum
lateral acceleration or MaxLat) by some margin. This should only
be applied to categories for which the Center of Gravity (CG) height
estimation based on roof height could be presumed to be reasonably
valid. This chart is for Stock, Street Touring, and Street Prepared
categories vehicles.
An approach of this type is required to help event officials assess the
rollover risk potential of vehicles which fall in a gray area between
traditional Solo® cars and those which clearly have a “high center of
gravity”. While it is imperfect, it should strike a balance between risk
reduction and admission of the most vehicles to Solo® while introducing a consistent procedure for doing so.
Section 3 — 33
The chart is for Regional Officials and Technical Inspectors to determine the acceptance level of high roll center vehicles referred to
in Section 3.1. The measurements are to be taken from the ground
to the tallest point of the vehicle for the Overall Vehicle Height and
the normal track measurement as stated in the GCR for the Average
Track Width.
Vehicles with a SSF less than 1.30 should not be permitted to compete in our Solo® events due to their higher risk of roll over.
As an alternative to SSF, the U.S. Department of Transportation
Rollover Rating may be considered as a criterion for acceptability. A
model with a rollover rating of 14% or less is considered acceptable.
Physically disabled drivers may use alternate vehicle controls and preparation items appropriate for the nature of their disability. In the case of
a driver using alternate controls, extra care should be taken to ensure
that the driver does have adequate control of the vehicle and that the
control mechanisms can stand up to competition use. A waiver from the
SCCA® Technical Services Department is required for the use of such
equipment in National Solo® events. Requests will be handled on a
case-by-case basis.
3.2 VEHICLE CLASSIFICATION
New car makes, types and models will be classified by the SEB as soon
as sufficient information is available to do so. The SEB may reclassify a
car within the 12-month period following its initial classification, without
the approval of the Board of Directors. “Initial classification” includes
the addition of a new listing on an exclusion list. Initial classification is
inclusive of a new listing on an exclusion list.
3.3 VEHICLE SAFETY
3.3.1 Driver Restraints
Seat lap belts are required in all cars, and must be installed in cars with
passive restraint systems that do not include a lap belt. Installation and
the use of shoulder belts or harnesses is strongly recommended, however non-factory upper body restraints may only be used in open cars,
cars with targa-tops in the open position, or cars with T-tops in the open
position when two conditions are met:
A. The roll structure must meet either the requirements of Appendix C
or the Club Racing General Competition Rules (GCR) 9.4.
B. The top of the roll structure may not be below the top of the driver’s
helmet when the driver is in the normal driving position.
3.3.2 Roll Bars
Roll bars or roll cages are strongly recommended in all cars. A roll bar
meeting the requirements of Appendix C or a roll cage meeting the
requirements of Section 9.4 of the Club Racing General Competition
Rules (GCR) is required in all A Modified (AM), B Modified (BM), C Modified (CM), and F Modified (FM) vehicles and all open cars in Prepared
Category, D Modified (DM) class, and E Modified (EM) class. For open
cars in the Stock, Street Prepared, Street Touring, and Street Modified
categories, the roll bar or roll cage height may be reduced from Appendix C or GCR 9.4 requirements to the highest possible height which
fits within an installed factory-specified hardtop or convertible top. The
roll bar or roll cage height may also be reduced in the same manner for
cars in the Prepared category with a full original equipment windshield
assembly and a standard (as defined herein) hardtop which has been
bolted securely in place.
Double-hoop roll bars must fasten properly to the chassis/unibody as
required by Appendix C, particularly at attachment points in the center
of the car.
3.3.3 Safety Inspections
All vehicles must pass safety inspection on the following points prior
to competing. Entry fees, if already paid, will be refunded if a car fails
to pass safety inspection. Safety inspection is not concerned with the
legality of a car.
The organizing Region may at its discretion provide an advisory inspection for vehicle classification and legality, in connection with technical
inspection.
A. Annual Inspection (optional)
An Annual Safety Inspection for a calendar year may be available
for vehicles presented for inspection by an SCCA® member. When
a vehicle has completed the requirements for an Annual Safety Inspection, an official Annual Tech card will be issued to allow Registration or other designated event officials to verify Annual Tech prior
to the start of competition. An official Region SCCA® Annual Tech
Section 3 — 35
sticker shall be placed on the vehicle in a location that will be visible
to the starter when the vehicle approaches the start line for a competitive run. If the Annual Tech sticker has been removed, the card
may be used to obtain a replacement. Alternatively, individual event
tech stickers can be issued when the Annual Tech card is presented
rather than the issuance of an Annual Tech sticker. The Annual Tech
should be honored for all SCCA® sanctioned Solo® events in that
Region. The following conditions apply to all Regional implementations of Annual Tech:
1) Regions have the option of placing additional restrictions on the
Annual Tech process, such as limiting the classes allowed and/or
restricting it to experienced drivers.
2) The Annual Tech inspection must be conducted by an experienced inspector appointed by the Regional Solo® chairperson. It
is strongly recommended the Region Tech Inspector appoint and
train an adequate number of assistants.
3) The vehicle should be presented for Annual Tech in the same condition in which it will compete.
4) It is the responsibility of all competitors in a vehicle with an Annual Tech approval to verify that all items in section 3.3.3 are in
compliance.
5) The event technical inspector or chairperson may require a vehicle be presented for a re-inspection if there is good reason to
believe that a vehicle is not in compliance with section 3.3.3.
6) A vehicle must be re-inspected if modifications are made to the car
after receiving an Annual Tech approval.
An official SCCA® Annual Tech sticker may be affixed to helmets
meeting the current standards in order to easily identify eligible helmets.
B. Inspection Requirements
1) All loose items, inside and outside the car, must be removed. Hand
held items, such as but not limited to, cameras and cell phones are
considered loose items.
2) Passenger’s seat back and all cushions, bolsters, headrests, etc.
must be secured. All allowed aftermarket replacement seats (i.e.,
driver and passenger) must be securely and safely mounted. Special care should be taken when using other than OE mounting points
and/or fabricated bracketry.
3) Any cameras, if installed, must be securely mounted to withstand
loads from driving maneuvers. The camera may be installed either
inside or on the outside of the car. In either case, its mounting method and position must not interfere with driving or pose an additional
hazard to driver, passenger, or course workers.
4) Snap-on hubcaps, detachable fender skirts, and trim rings must be
removed.
5) Wheels must be safely affixed. They shall not be reversed so that the
lughole taper does not mate with the chamfer of the lugs. All studs
and lug nuts must be present and functional.
6) Tires must be in good condition, with no cord or belts showing or
cracks in the tread or sidewall. Each tire must have measurable (i.e.,
exhibiting positive measurement values) tread depth at no less than
two points on the tire which are 180 degrees apart around the circumference, and which are within the center one-half of the tread
surface that normally contacts the ground. Tires may not have cord
visible at any time during competition. For categories other than Prepared and Modified, tires may not be re-grooved, nor may grooves
be added to the tread pattern where none existed on the original tire.
7) Seat belts (and harnesses if used) must be properly installed with attaching hardware, in good condition, secure, tight, and in compliance
with Section 3.3.1.
8) Throttle return action shall be safe and positive.
9) No excessive fuel, oil, water or brake fluid leaks should be observed.
For all Prepared and Modified category vehicles, engine crankcase
and radiator overflow/breather lines must terminate in containers of
at least one quart capacity. These containers cannot be vented into
the driver/passenger compartment. All Prepared and Modified category vehicles must be equipped with an engine oil vent tank and
an engine coolant vent tank if coolant is used. Vent tanks are not
required with systems which are completely closed, i.e. have no
venting to the atmosphere. All oil lines passing through the driver/
passenger compartment shall be made of metal braided hose or
equivalent (e.g., Nomex, Kevlar, or nylon-braided hose) with AN Series threaded couplings or entirely covered and protected with a metal cover (this does not apply to the small oil lines used for mechanical
oiling system gauges).
10) Steering “spinner” knobs shall not be permitted.
11) No broken or missing spokes or more than one loose spoke per
wheel shall be permitted in wire wheels. No cracks shall be permitted
in disc or cast wheels. Other than standard parts as defined by these
rules, non-metallic wheel construction is prohibited (FSAE cars are
exempt from this requirement since the FSAE rules allow non-metallic wheels).
12) Brakes must have an adequate pedal, sufficient fluid in the master
cylinder, and no apparent hydraulic leaks under pressure. Vehicles
must have a brake mechanism acting upon each wheel. The braking system shall be a dual system, arranged in a manner to provide
braking for at least two wheels in the event of failure in part of the
system. In the case of OE single systems, this requirement may be
satisfied by a functional, redundant emergency brake. Karts are exempt from this requirement.
Section 3 — 37
13) All swing axle cars, except Porsche, must have a camber compensator, have negative camber on the rear wheels, or have axle-limiting
straps. Standard pre-1967 Volkswagen straps are not sufficient.
14) Wheel bearings, shocks, steering, and suspension shall be in good
operating condition.
15) Exhaust must exit behind driver or to the side of the car.
16) On-board starters shall be provided.
17) Any wet-cell battery moved from the manufacturer’s original location shall be in a non-conductive, marine-type container or equivalent and the “hot” terminal shall be insulated. All batteries (on-board
power supplies) shall be attached securely to the frame or chassis
structure independent of the marine-type container. NOTE: This will
allow the use of gel cell or dry cell (AGM) batteries without a nonconductive, marine-type container where applicable.
18) Roll bars, if installed, must meet the applicable portions of 3.3.2 and
Appendix C with specific attention to roll bar height.
19) Helmets for all occupants of the vehicle are to be inspected for condition, fit, and compliance with section 4.3.1 Driver’s Safety Equipment - Helmets.
20) Flex fans are not allowed.
21) Alcohol may not be used in manifold injection or spray bottles unless it is specified for this use by the OEM.
22) For cars competing on non-DOT-approved tires, the vehicle safety
requirements as referenced in each category rule set, in addition to
those in mandatory sections of the Solo Rules, shall be adhered to
by all entrants.
23) A vehicle must meet the requirements of 3.3.2 as they apply to all
categories in which it is entered.
24. For all karts, chain guards are required on engines.
25. For all karts, a “brake safety cable” or redundant brake pedal connection is required.
3.3.4 Vehicle Operating Condition
Any car that is judged by the Event Chairman to be in an unsafe operating condition at any time during the event shall be barred from further
competition until the deficiency is corrected to the satisfaction of the
Chief Technical Inspector.
3.4 LIMITED AVAILABILITY OPTIONS
The SEB may designate limited availability option packages as inappropriate for the Stock Category even though the base car is eligible
for Stock. Such exclusions will be included in Appendix A (Automobile
Classes).
3.5 MUFFLERS
Adequate mufflers are required for Solo® events. The criterion of “adequacy” is not what the exhaust system consists of, but the sound level.
Any car deemed by the Event Chairman or his designated representative to be excessively loud shall not compete without acceptable modifications installed on the car.
3.6 FUEL
A. Stock and Street Touring category vehicles will use service station
pump fuel only. Pump fuel is defined as that which is “Federally approved for use on public highways.” This includes the pump fuel
known as E85, but does not allow racing-type fuels which are available at service station pumps.
B. In addition to fuels which are allowed by 3.6.A, Street Prepared,
Street Modified, Prepared, and Modified category vehicles may use
diesel fuel or any grade of gasoline. Gasolines consist entirely of
hydrocarbon compounds. Gasoline may contain antioxidants, metal
deactivators, corrosion inhibitors, and lead alkyl compounds such as
tetraethyl lead. Oxygen and/or nitrogen bearing additives are prohibited except for those originally present in service station pump fuel.
Oxygen and/or nitrogen bearing oil additives are prohibited in twocycle engine oiling systems.
C. Propane or CNG (compressed natural gas) fuel may be used in any
category provided that the following conditions are met:
1. The tank must be located in a safe location on the car, and be firmly and securely mounted. This does not permit the cutting of vehicle sheet metal, e.g. the trunk floor, for tank installation in Stock,
Street Touring, Street Prepared, or Street Modified categories.
2. The tank must conform to Federal and local container standards
and have an emergency relief/cut-off control.
3. For use of propane or CNG as fuel, no changes to the induction
system of the engine may be made with the exception of the necessary fuel lines to the carburetor or fuel injection. There may also
be no other engine parts changed.
4. The entire system must meet local ordinances covering the use
and transmission of compressed gas.
5. Propane or CNG may not be used in combination with another
fuel.
3.7 VEHICLE IDENTIFICATION
A. All vehicles must display numbers and class letters on both sides,
which must be readable by Timing & Scoring, Course, and Grid
workers at all times.
B. Only one set of numbers and class letters may be visible while the
vehicle is running.
C. Class shall be represented by the upper-case abbreviated form rather than be spelled out. Ladies’ classes shall be indicated by the letter
Section 3 — 39
“L” following the class letters. (Example: “BSPL” instead of “B Street
Prepared Ladies”).
D. Numbers and class letters should be positioned next to each other.
All letters and numbers must be on body panels, not on windows.
All numbers and class letters must use the same typeface and the
same color, and this color must provide adequate contrast to the
background color (see Appendix F for examples).
E. Numbers must be a minimum of 8” high with a 1.25” stroke. Class
letters must be a minimum of 4” high with a 0.75” stroke. In all cases,
the height of the class letters must be between 25% and 75% of
the height of the numbers. Stroke width must be at least 10% of the
height (see Appendix F.)
F. The “1” on two-driver cars and the “L” on Ladies class cars are subject to all of the above requirements with regard to placement, color,
size, and stroke.
G. Karts may use numbers and class letters of reduced size provided
that the following conditions are met:
1) Numbers must be displayed on the front and rear in addition to
both sides.
2) Class letters must be on both sides.
3) In no case may the numbers be smaller than 6” in height with ¾”
stroke, using a high-contrast color and background.
H. For National Championship and National Tour competition, current
official SCCA® required decals must be displayed on each side of
the vehicle in a prominent location.
For National Championship and National Tour events, one (1) official SCCA®-approved National sponsor identification logo must be
displayed in an upright position, in a prominent location on each side
of the vehicle. Additional sponsor and/or event specific decals may
also be required; refer to event supplemental regulations. Further
information is contained in Appendix F.
3.8 REQUIRED DOCUMENTATION
The entrant has the burden of proving that the vehicle conforms to
these Rules by the required documentation for the category/class, as
noted below. The required documentation should be considered as an
extension of these Rules.
A. Stock, Street Touring, Street Prepared, and Street Modified – The official manufacturer service documentation for the make, model, and
year of the vehicle as entered, if ever available to the consumer from
the manufacturer. Additional official manufacturer service documentation for other years and/or models may also be required to cover
equipment and/or specifications authorized by update/backdate allowances. Other official manufacturer documentation, such as the
owner’s manual, shop manual, parts catalogs, technical bulletins,
sales & marketing literature, or Monroney window sticker, may be
provided as supporting information. All manufacturer documentation
must be for non-competition purposes.
B. Cars prepared to SCCA® Club Racing rules (Showroom Stock, Improved Touring, American Sedan, Touring, Spec Miata, Production,
GT, Formula cars, Sports Racers, etc) – Current year GCR and appropriate Category Specifications plus any additional documentation
required by those rules. Logbooks are not required.
C. Prepared category, A Modified class (AM), D Modified class (DM),
and E Modified class (EM) – No additional documentation required.
D. Kart Modified (KM) and Formula Junior (FJ):
World Formula karts – Briggs & Stratton Performance Guide and
Racing Log which includes specifications and part numbers.
Other approved karts – Technical manual including the specifications
to which the kart was prepared.
E. Formula SAE (FSAE) – Applicable FSAE Specifications.
4. DRIVERS AND CLASSES
4.1 DRIVER’S CREDENTIALS
A. Drivers must possess a currently valid automobile driver’s license.
Any underage driver who has the legal authority (license or permit)
to operate an automobile with restrictions on a public road may compete in a Stock, Street Touring, or Street Prepared class at Regional
events, as long as the restrictions of the driving license or permit are
met. If those restrictions require a passenger and the Region allows
a passenger, that passenger must be either the driver’s parent/legal
guardian or an approved instructor. That instructor must be approved
by both the event chairman and the event Solo® Safety Steward
on a case-by-case basis. He/she must have the written permission
of the driver’s parent/legal guardian (signed at the event) to ride as
a passenger and the restrictions imposed by the underage driver’s
state must allow the instructor to ride as a passenger. Drivers must
be SCCA® members.
B. Drivers are responsible for knowing and understanding the SCCA®
National Solo® Rules. Ignorance of the Solo® Rules will not be accepted during any adjudication of issues regarding event operations,
vehicle compliance, driver/crew behavior, or any other topics. It is
strongly recommended that competitors have a copy of the current
Solo® Rules at all SCCA® Solo® events, especially at National
events.
C. Any competitor or worker with a known medical condition (including
pregnancy) which could affect his/her ability to compete may do so
only with the concurrence of his/her personal physician.
D. The event organizers have the right to refuse an entry at their discretion. This permits organizers to protect themselves and their programs by declining the entry of someone who is believed to pose a
Section 4 — 41
safety hazard or other significant threat. For this purpose the event
organizer is defined as:
Regional Event: Event Chairman or Region Solo® Chairman
National Tour and Championship Events: Committee of Vice President of Rally/Solo®, Event Chairman, and SEB Chairman
ProSolo®: Vice President of Rally/Solo® or designee
4.2 EVENT ENTRY
Entry into all SCCA® Solo® events is limited to those individuals meeting the mandatory sections of the Solo® Rules. Additional entry requirements follow.
A. Regional Events – Requirements are determined by the Region organizing committee.
B. National Solo® Events – Drivers in National Solo® events must be
individual, spouse, family, or First Gear SCCA® members. Except
for the Solo® National Championships, a Weekend Membership
meets these requirements.
C. National Solo® Entry Fees
1. The entry fee shall be paid only with cash, check, money order,
Discover, MasterCard, or Visa. There will be a handling charge
for phone entries. Cancellations must be made in writing (fax to
785-861-1713 or email to solo@scca.com is acceptable) to the
SCCA® National Office. Entry forms, updated deadlines, and refund requirements for all events will be on the SCCA® web site
(www.scca.com). Completed entry forms are to be sent to the

Formula Junior drivers must use helmets meeting the above, SFI 24.1
(Youth Helmets), Snell CMR2007 (Children’s Motorsports Restricted),
or Snell CMS2007 (Children’s Motorsports Standard) specifications.
For maximum protection, helmets must fit securely and should provide
adequate peripheral vision. The chin strap must be securely fastened.
Loaner helmets should be available to vehicle occupants not having
their own.
4.3.2 Seat Belts
Driver restraints complying with section 3.3.1 shall be worn while on
course. The “CG-Lock®” is considered compliant for use in all applicable categories.
4.3.3 Eye Protection
Face shield, goggles, or similar face protection (conventional eyeglasses are not sufficient) shall be worn while competing in a sports racing
car, formula car, special, or any car with less than a standard-size windshield.
4.3.4 Footwear
Shoes covering the entire foot shall be worn.
4.4 CAR/DRIVER LIMITS
A. A driver may enter an event only once.
B. A given car may be entered by no more than two (2) drivers in the
same class.
4.5 CAR/DRIVER CHANGES
If during the event a vehicle develops mechanical problems resulting in
its permanent withdrawal from the class heat competition, its driver(s)
may finish his/her (their) runs in another vehicle which is compliant in
that class. Drivers needing to finish their runs in another vehicle, as
permitted by this allowance, must obtain the approval of the Operating
Steward.
A driver may change cars prior to the beginning of competition until
the driver’s class heat begins, at the discretion of the Chief Steward or
Chief of Registration in consultation with the Chief of Timing.
4.6 RESPONSIBILITY FOR CAR CLASSIFICATION
The driver is responsible for the correct determination of the car’s class/
category. If in doubt as to classification or concerning the conformity
of the car or its equipment to the rules governing the class, he/she
may submit a Request for Clarification to the Protest Committee, which
will determine the matter under the procedures of Section 8. It is the
driver’s responsibility to assure the proper number is on the car prior to
competing.
4.7 LADIES CLASSES
A. Parallel Ladies classes will be provided for females who wish to enter
them.
B. Females will have the option of running in the Open classes.
C. Scoring for the Ladies classes will be handled in the same manner

Section 4 — 43
4.8 DEFINITION OF CLASS TYPES
A. National Class – Any class defined in this rule book that is recognized as eligible for a National Championship. This explicitly does
not include Supplemental classes. These classes are automatically
offered at National Tour and National Championship events. In determining whether or not a class will achieve National Class status, that
class will be evaluated on whether it:
1. has at least 25 participants (Open and Ladies Classes) for 3 of 4
consecutive National Championships or
2. has at least 40 participants (Open and Ladies) for 2 of 3 consecutive National Championships or
3. fits with the long-term vision for the continued growth of Solo® according to Introductory Section I.2.3 of the Solo® Rules.
B. Supplemental Class – Any non-National class running under a proposed rule set for purposes of evaluation. It may be run alone or within a parent class. Its drivers may or may not be eligible for awards.
C. Regional Class – Any class not listed in these Solo® Rules but created by a Region or other entity for local purposes.
4.9 MINIMUM PARTICIPATION LEVEL FOR NATIONAL CLASSES
If in three consecutive years at the Solo® National Championship a
class fails to field a combined total (Open and Ladies) of at least seventeen (17) entrants, then for the following year that class will be amended. Changes to be considered may include, but are not limited to:
a) competition adjustments (i.e., weights and/or wheel sizes), if applicable within the affected category.
b) consolidation.
c) restructuring.
d) elimination.
This is not intended as the only criterion for class adjustments, consolidation, elimination, or restructuring; the SEB may pursue such actions
as deemed necessary to address participation problems. The SEB may
take into account participation levels at other events such as National
Tours when making decisions regarding the need for changes. Modified
Class A (AM) is exempt from this requirement.
4.10 CONFLICT OF INTEREST
No person may compete who has pre-run through all or any part of the
course, in or on any wheeled vehicle, except a competitor with a physical disability that impairs his/her ability to walk may, with the approval
of the Chief Steward, use a wheelchair or similar aid (which does not
include a bicycle) traveling at normal walking speed to accomplish the
requirements of section 6.3. All event officials, whether competing in
the event or not, must use caution to avoid individual conflict of interest
situations during the event.
4.11 MEDICAL
Any competitor with a known medical condition (including pregnancy)
which could affect their ability to compete may do so only with the concurrence of their personal physician.
4.12 LICENSES AND SOLO® PASSPORT
All licenses will expire on the membership anniversary date and will be
renewed by Member Services upon receipt of a completed application
and license fee. Currently, there are no applicable licenses for Solo®
events and/or participation at the time of publication.
The Solo® Passport is a benefits package which expires at the end of
the calendar year.
4.13 ASSUMPTION OF RISK
Solo® is a potentially dangerous activity that can result in serious injury
or death. Participation in all aspects of the activity is voluntary. The
ultimate responsibility for participant and vehicle safety lies with the participant, vehicle owner, driver, and crew members.
The participant agrees that by entering an event, the participant has
had the opportunity to inspect the event site and acknowledges that the
event site is safe and suitable for competition. The participant also acknowledges that by participating in the event, the participant may suffer
bodily injury or death, or loss or damage to property. The participant further acknowledges that the participant has voluntarily assumed the risk
of bodily injury or death or loss or damage to property and waives any
claims for bodily injury or death, or loss or damage to property against
SCCA®, its directors, officers, employees/agents, event officials, event
sponsors, racetrack operators, site owners/operators, and other participants; discharges such persons and entities from responsibility for such
losses; and covenants not to sue such persons and entities for bodily
injury or death or loss or damage to property.
4.14 INSURANCE RELEASE AND WAIVER
A. ADMINISTRATIVE PROCEDURES (Refer to Introductory Section
I.10 of these Rules, page 21)
In accordance with the SCCA® insurance guidelines, all competing
and non-competing participants at or over the age of majority in the
state in which the event is being conducted must sign a Release and
Waiver of Liability, Assumption of Risk, and Indemnity Agreement
(form MS-1). Those under the age of majority must have a completed Minor Release and Waiver of Liability and Indemnity Agreement
(form MS-2A) on file with an SCCA® Registrar/Region. All competitors, except participants in the Junior Driver program, must also have
a valid driver’s license.
For competitors, the Minor Waiver form must be signed by both
parents/legal guardians if the minors are to be drivers/passengers.
Section 4 — 45
For non-competitors, the form may be signed by only one parent/
legal guardian on a per-event basis. If signed by both parents/legal
guardians and properly filled out to apply to “ALL EVENTS” and “ALL
DATES,” the form is valid at all SCCA® Solo® events held in that
SCCA® Region. A new waiver must be signed each calendar year.
However, it is agreed and understood by the signatory/signatories
that the prior year’s waiver form’s validity is not affected by the failure
to do so.
All parent/legal guardian signatures must be witnessed by an adult
SCCA® member. The SCCA® Region may, at its discretion, require
that any form completed off-site be notarized.
Copies of the original Minor Waiver form may be used at individual
events or for calendar year/annual waivers. A Minor Photo ID card
may be issued by the Region for that calendar year. Minors may not
attend non-spectator events without a properly completed waiver.
B. EXECUTION OF REQUIRED FORMS and RELEASE AND WAIVER
OF LIABILITY, ASSUMPTION OF RISK, AND INDEMNITY AGREEMENT
As set forth above, all participants or, where applicable, the parents/
legal guardians shall be required as a condition of participation to
sign all required entry forms including but not limited to such releases as shall be required by SCCA® and/or its insurers consisting of
the following or similar wording. Whether or not the participant or,
where applicable, the parents/legal guardians sign(s) such releases,
the participant or, where applicable, the parents/legal guardians on
behalf of a minor participant agree(s) to the terms set forth below
and any participant is hereby put on notice of such terms and makes
such agreement and/or acknowledges the terms of the below either
by receiving this Rulebook or by participating in an SCCA® event,
or both.
IN CONSIDERATION of being permitted to compete, officiate, observe, work for, or participate in any way in any Sports Car Club
of America® or SCCA Pro Racing® (“SCCA®”) events or activities
(EVENTS), or being permitted to enter for any purpose any RESTRICTED AREA thereof (defined as any area requiring special authorization, credentials, or permission to enter or any area to which

inspect the RESTRICTED AREAS and/or EVENT course and facilities (including adjacent areas thereof) with which I may contact
during the EVENT prior to my participation and that there may be
risks not known to me or that are not foreseeable at this time. I
agree that, if at any time, I feel anything to be UNSAFE, I will immediately take all necessary precautions to avoid the unsafe area
and REFUSE TO PARTICIPATE further in the EVENT.
2. Hereby RELEASE, WAIVE, and DISCHARGE SCCA, the promoters, participants, racing associations, sanctioning organizations
or any affiliate, subsidiary or subdivision thereof, track operators,
track owners, officials, car owners, drivers, pit crews, rescue personnel, any person in any RESTRICTED AREA, sponsors, advertisers, owners and lessees of premises used to conduct the
EVENTS, premises and event inspectors, surveyors, underwriters, consultants and others who give recommendations, directions, or instructions or engage in risk evaluation or loss control
activities regarding the premises or EVENTS and for each of them,
their directors, officers, agents, and employees, all for the purposes herein referred to as “RELEASEES,” FROM ALL LIABILITY
TO ME, my personal representatives, assigns, heirs, and next of
kin FOR ANY AND ALL LOSS OR DAMAGE, AND ANY CLAIM
OR DEMANDS THEREFOR ON ACCOUNT OF INJURY TO THE
PERSON OR PROPERTY OR RESULTING IN THE DEATH OF
THE UNDERSIGNED ARISING OUT OF OR RELATED TO THE
EVENTS, WHETHER CAUSED BY THE NEGLIGENCE OF THE

the RELEASEES arising out of my injury, or death, or damage to
my property while I am in the RESTRICTED AREAS and/or while
competing, practicing, officiating, observing or working for or for
any purpose participating in the EVENTS and whether caused by
the negligence of the RELEASEES or otherwise.
5. Hereby acknowledge that THE EVENTS ARE POTENTIALLY
VERY DANGEROUS and involve the risk of serious injury and/or
death and/or property damage. I also expressly acknowledge that
INJURIES MAY BE COMPOUNDED OR INCREASED BY NEGLIGENT RESCUE OPERATIONS OR PROCEDURES OF THE
RELEASEES.
Section 4 — 47
6. Hereby agree that this Release and Waiver of Liability, Assumption of Risk and Indemnity Agreement extends to all acts of negligence by the RELEASEES, INCLUDING NEGLIGENT RESCUE
OPERATIONS and is intended to be as broad and inclusive as
is permitted by the laws of the Province or State in which the
EVENTS are conducted and that if any portion thereof is held invalid, it is agreed that the balance shall, not withstanding, continue
in full legal force and effect.
I HAVE READ THIS RELEASE AND WAIVER OF LIABILITY, ASSUMPTION OF RISK, AND INDEMNITY AGREEMENT, FULLY UNDERSTAND ITS TERMS, UNDERSTAND THAT I HAVE GIVEN UP
SUBSTANTIAL RIGHTS BY SIGNING IT, AND HAVE SIGNED IT
FREELY AND VOLUNTARILY WITHOUT ANY INDUCEMENT, ASSURANCE, OR GUARANTEE BEING MADE TO ME AND INTEND
MY SIGNATURE TO BE A COMPLETE AND UNCONDITIONAL
RELEASE OF ALL LIABILITY TO THE GREATEST EXTENT ALLOWED BY LAW.
5. OFFICIALS
5.1 CHIEF STEWARD (TOUR AND NATIONAL CHAMPIONSHIP)
A Chief Steward shall be appointed for all Solo® National Tour and
National Championship events. This person shall be responsible for
ensuring that the general conduct of the event is in accordance with
the Solo® Rules and the supplementary regulations for the event. After
the start of the event, the authority of the Chief Steward shall supersede that of the Event Chairman regarding the effectiveness of event
administration procedures in achieving the intent of all applicable rules.
However, selection of event administrative procedures remains the responsibility of the Event Chairman as long as those procedures achieve
compliance with the Solo® Rules and event supplementary regulations.
The Chief Steward is recommended to be a member of an SCCA® Region other than the host Region.
The Chief Steward shall:
A. Be appointed by the National Solo® Department for National Tour
events and the SEB for the National Championship event. Examples
of an individual qualified to be appointed to this position are past or
present SEB member, DSS, or National and Divisional Chief Steward from the Club Racing program with a working knowledge of the
Solo® Rules.
B. Prohibit entry of any vehicle not meeting Tech requirements as reported by the Chief Technical Inspector.
C. Report to the Protest Committee any vehicles found non-compliant
during Impound as reported by the Chief of Impound.
D. Not serve in any other official capacity during the event.
E. Appoint an Operating Steward for the event.
F. This position shall be filled by an SCCA® member.
5.2 OPERATING STEWARD
The Operating Steward is responsible for executing the plans and procedures established by the Event Chairman and DSSS to successfully
complete the program of competition. The Operating Steward will be
appointed by the Chief Steward and may be a member of the host Region. If the Operating Steward believes a change in event procedures is
necessary to achieve compliance to the Solo® Rules and supplementary regulations, the Operating Steward shall recommend appropriate
modifications to the Chief Steward for approval. If approved, the Operating Steward will implement the modifications. This position shall be
filled by an SCCA® member.
5.3 EVENT CHAIRMAN
The Event Chairman is the chief planner and organizer of the event.
The Event Chairman shall design and establish, or oversee development of, all necessary event administrative process including:
A. Establishing event administration procedures that achieve compliance with all applicable Solo® Rules and supplementary regulations,
including a waiver signing system.
B. Formulating procedures to implement the plans of the DSSS for ensuring spectator, driver, and worker safety.
C. Design, layout, and pre-running of a suitable course. (EXCEPTION:
The approval of the design and layout is the responsibility of the SEB
for the National Championship event and the Solo® National Office
for Tour events.)
At controlled-access event sites, appoint SCCA® members to control entry access by having all persons sign the release & waiver
form and receive a signature credential (wristband or similar means
of identification) before entering the event site.
For uncontrolled-access event sites, appoint SCCA® members to
assure that competitors, workers, crew, and guests have signed the
release and waiver form and received a signature credential (wristband, hardcard, or similar means of identification). Shall also appoint
workers equipped with forms and credentials to continually survey
the event site for non-credentialed people.
The SSS will verify that the Event Chairman has a system in place
to assure that persons at the event site have signed the release and
waiver form and received a signature credential. Further, the SSS
will ensure that the release and waiver form has the event, the date,
and the signatures of the SCCA® member witnessing the participant’s signatures.
D. This position shall be filled by an SCCA® member.
Section 5 — 49
5.4 SOLO® SAFETY STEWARD
The Solo® Safety Steward (SSS) will also verify that the Certificate of
Insurance is present at the event site and correct before the event begins. If this is not in order, the SSS must confirm corrections or issuance
of the certificate with SCCA® Risk Management prior to the start of the
event. If outside of business hours, the SSS must call the Insurance/
Incident Emergency Number, 1-800-770-9994.
The duties of the SSS shall concern the safety of the spectators, workers, and driver safety relative to course design. Control over course design extends only to such issues as course or near-course hazards and
not to design philosophy. In Solo® events, safety issues are those such
as listed in sections 1.3 and 2.1. This includes course security, which
is defined as maintaining control over spectator access to the course.
This position shall be filled by an SCCA® member who is 18 years of
age or older.
5.5 CHIEF OF WAIVERS
The Chief of Waivers shall be responsible for ensuring that the waiver
function complies with the requirements of the SCCA® insurance coverage as regards Solo® events. Specifically, the Chief of Waivers shall
ensure that the following are met:
A. The waiver function follows the Solo® National Office guidelines.
B. All waivers used at an event are correctly signed, witnessed, and
completed, including the event designation, location, date, and all
required signee and witness information.
C. Necessary supplies and equipment are maintained as applicable.
D. Waiver workers are on duty from the time the gate or site is opened
until the event has been completed.
E. Waiver workers have been recruited, trained, and assigned in cooperation with the Chief of Workers.
F. Waiver workers are SCCA® members.
G. Communication is provided between the waiver station(s) and event
administration.
H. Waivers are properly stored for the number of years required by the
Solo® National Office guidelines and local laws.
This position shall be filled by an SCCA® member. It is strongly recommended that the Chief of Waivers perform no other duties for the event.
5.6 CHIEF TECHNICAL INSPECTOR
The Chief Technical Inspector shall be responsible for ascertaining that
the vehicles comply with the requirements of the Solo® Rules and the
Supplementary Regulations. Specifically, the Chief Technical Inspector
shall ensure that the following tasks are performed:
A. Inspect for and certify that vehicles and driver safety equipment comply with all safety regulations.
B. Conduct inspections of automobiles at the request of the Chief Steward.
C. Report to the Chief Steward any automobiles that he finds do not
conform to requirements of the Solo® Rules or the Supplementary
Regulations.
D. Ensure that the appearance of each automobile is neat and clean.
Automobiles that are not presentable will not be allowed to compete.
The Chief Technical Inspector is not responsible for car classification;
that responsibility falls to the entrant as described in Section 4.5. This
position shall be filled by an SCCA® member.
5.7 CHIEF OF TIMING AND SCORING
The Chief of Timing and Scoring is responsible for accurately taking,
reading and recording times, posting them conspicuously during the
event and preparing the official results. This position shall be filled by
an SCCA® member.
5.8 CHIEF OF COURSE
The Chief of Course is responsible for observation of competing cars
on course, lining cars up for entry onto the course, providing starting
signals, directing cars off the course at the conclusion of a run, crowd
control, and for roping off the course or otherwise providing barriers so
that the course complies with Section 2. This position shall be filled by
an SCCA® member.
5.9 CHIEF OF IMPOUND
The Chief of Impound is responsible for procedures described in section 6.10 to verify vehicle compliance with the Solo® Rules and Supplementary Regulations. The Chief of Impound will conduct inspections of
vehicles independently or at the request of the Chief Steward and will
report to the Chief Steward any vehicles found not to be in compliance
with the Solo® Rules or Supplementary Regulations. This position will
be filled by an SCCA® member.
5.10 CHIEF OF PROTEST
The duty of the Chief of Protest is to provide leadership to the Protest
Committee and to provide notification of protest decisions to the parties
involved, i.e. the protestor(s) and protestee(s). He/she may or may not
elect to vote on protest rulings. He/she may also be a driver in the same
event, but will perform no other duties for the event.
5.11 PLURALITY OF DUTIES
The same person may hold more than one official position except that
the Chief Steward and the SSS may not serve in any other official capacity.
Section 5 — 51
6. EVENT OPERATION
6.1 ENTRANTS AS WORKERS
At National Solo® events, the entrants may be required to work. The
method by which the entrants may be required to work will be described
in the event Supplementary Regulations. Failure to work will result in
disqualification from the event.
6.2 COURSE MAP
A map of the course, showing all markers, the proper course, approved
optional courses, solid objects, and potential problem areas, will be
posted prior to the start of the event. The course configuration must be
the same for all drivers in a class.
6.3 COURSE FAMILIARIZATION
Each driver will be provided an opportunity to walk or drive through
the course or to have a parade lap before his first official run. See also
Section 4.10.
6.4 LEMANS STARTS FORBIDDEN
No start or finish shall be used wherein the driver is not seated in the
vehicle with seat belt buckled.
6.5 TIMING POINTS
A. A car will commence its run at least 15 feet before the point at which
timing begins.
B. Time at the end of the run will be taken in a manner which complies
with Section 2.1.J.
It is recommended that an official be assigned to control the finish area.
A complete stop is not required at the finish if sufficient area is available to safely halt any competing car without locking brakes or wild
maneuvering (from the highest possible speed attainable at the finish).
Particular care must be exercised in the finish area to keep it free from
hazard to participants and non-participants.
6.6 REPLACEMENT OF MARKERS
Displaced markers will be replaced before the next competitor enters
that portion of the course. Where an official run covers all or part of the
course twice, course marshals should have extra markers so that markers displaced during the first part of the run can be replaced before the
competing car returns to that section. If a driver encounters his/her own
displaced marker(s), he/she may not stop and receive a rerun.
6.7 VISUAL OR ORAL INSTRUCTION
No visual or oral instruction shall be given to a driver during his timed
runs except in an emergency situation.
6.8 ORDER OF RUNNING
Cars may run in any of the following orders, as specified in the supplementary regulations:
A. All cars will take their first runs and then all cars will take their second
runs in either the same or reverse order.
B. Cars will run in heats of a specified number (approximately 25 is recommended), with all cars in the heat taking all runs before the next
heat begins its runs.
C. Cars will run by classes with each class taking all of its runs before
the next class takes its runs. The advance publicity shall specify the
earliest time each class will run. Drivers will be responsible for being
present for their runs and no out-of-class runs will be granted.
D. Cars will run by groups of classes, for example: A Stock (AS), B Stock
(BS) and C Stock (CS), with all cars in AS taking their first runs, then
BS taking its first runs, followed by CS, before AS takes its second
runs, etc. The group will take their runs before the next group begins
its runs. NOTE: In National Championship and Tour events, all cars
shall run in class whatever method is used. The supplementary regulations shall clearly indicate the method of running, the order in which
the classes will run, and the procedure for two-driver cars.
Drivers of cars with mechanical difficulty shall have ten (10) minutes
after the car is scheduled to start to present a car at the start line.
Drivers may take one (1) mechanical delay per run. For this purpose,
a rerun counts as a new run. Grid personnel will be notified of the
mechanical difficulty, and will refer the request for a mechanical delay to the Chief Steward in cases where the competitor may gain an
unfair advantage by delaying a run. Abuse of this allowance may be
considered unsportsmanlike conduct and is protestable under section 9.1.F.
E. It is strongly recommended that a Ladies Class not be run in close
proximity to its appropriate Open Class. If both classes are running
in the same heat, the Ladies Class should be separated by as much
time as possible from the appropriate Open Class; however, it is still
preferable to run the two classes in different heats whenever possible.
6.9 SCALES
For National Solo® events, the Solo® National Office will make provisions to have official scales available for weighing of cars. The location
of the scales will be included in the event supplementary regulations
and the scales will be available during the event, though not necessarily
free of charge.
6.10 IMPOUND
All competitors (vehicle with driver or driver’s representative) will be
impounded with their class after competing until released by the Chief
of Impound or an official designee. While in Impound, vehicles in all
Section 6 — 53
categories except Modified, Kart Modified, and Formula Junior must
have hoods and trunks fully opened. During this time competitors may
visually inspect each other’s vehicles.
The SCCA® reserves the right of its designated representatives to ensure the legality of competing vehicles.
All vehicles in classes subject to weight requirements and in trophy
positions as determined by the official results will be weighed. If there
is any question about compliance with weight requirements, the vehicle
will be weighed in both directions.
The Chief of Impound or designated representative(s) may conduct
other inspections as allowed by 5.9.
The Chief of Impound will notify the Chief Steward of any non-compliant
concerns or irregularities discovered in these inspections or of any entrants or competitors who do not follow Impound procedures.
6.11 PREHEATING TIRES
Pre-heating of tires prior to competition by electrically heated covers or
by similar means is prohibited.
7. TIMING AND SCORING
7.1 STANDARDS
7.1.1 Timing Standards
Events shall be timed to the nearest 1000th of a second (0.001 sec).
7.1.2 Scoring Standards
For a multi-course event, a competitor’s score shall be the total of his/
her best time on each course. In the event a competitor does not have
a time on a course, he/she shall receive a DNF for the event.
7.2 TIMING SYSTEMS FOR NATIONAL SOLO® EVENTS
There shall be at least two (2) operable electronic timing systems per
course at the Solo® National Championship. The Chief Steward will
establish the timing accuracy between the systems prior to the beginning of the runs. One system will be designated the primary system
and all times listed obtained from such system. In the case of a primary
system failure, the secondary system shall be used, with appropriate
time corrections being made prior to the listing of the times, until the
primary system can be activated and utilized. Alternate systems and
procedures may be approved by the SEB.
7.3 MINIMUM OF THREE RUNS
Each driver shall be allowed at least three (3) official timed runs per
course, subject to severe circumstances beyond the control of the
event organizers. Reduction in the number of runs offered at the National Championships may be done only with the concurrence of the
Chief Steward, Event Chair, SEB Chair, and the Solo® National Office.
Only the fastest official run per course will be scored.
7.4 RERUNS
Reruns will be granted only for timing failure, object on the course, red
flag, or other situations at the discretion of the Chief Steward and will
not be given because of mechanical or other failure of the competitor’s
car. A minimum of five (5) minutes must have elapsed before a competitor may take a rerun.
Pylon penalties are not carried over to the rerun. A DNF on a run for
which a rerun would have been given shall stand and no reruns shall
be given.
In the case in which a competitor is red-flagged or stops for a displaced
or downed cone on the course, the competitor may continue slowly
through the remainder of the course or may exit the course directly and
will be granted a rerun if appropriate. Failure to exit the remainder of the
course at an appropriately reduced speed (generally 79-80% of competition speed) will result in a DNF for that run. It is important to clear the
course in a timely manner in order to avoid impeding the progress of the
car following and ensure the event remains on schedule.
7.5 TIMER FAILURE
If the timer fails to start or fails during a run, the driver must be flagged
off the course as soon as possible.
7.6 TIES
Ties for trophy or point scoring positions shall be broken by comparing
the next fastest runs from each course. The times will be combined and
then compared to break a tie. If the tie persists, it shall be broken by a
runoff, provided both contestants agree. If agreement is not reached,
the tie shall stand. The additional run shall be used only to break the
tie, and shall not be used to place either contestant in a position other
than those tied for.
7.7 LUCK OR CHANCE
Luck or chance, or gimmicks, such as balloon bursting, may not be deliberately included as a factor in judging in National Tour and National
Championship events. Regional events may use such gimmicks if that
fact is clearly stated in advance publicity and the supplementary regulations for the event.
7.8 SCOREBOARD
A scoreboard must list the driver’s name, car number, class, corrected
times, and penalties. In National events, the times and penalties for
each competitor must be posted prior to the next run of that competitor.
7.9 PENALTIES
7.9.1 Course Markers (Pylons)
A clearly visible line around the base will mark the location of each pylon. The inner edge of the line will be used to describe the outer edge
Section 7 — 55
of the pylon base as accurately as possible and this inner edge will be
the penalty limit. If the pylon is upset or totally displaced outside the
penalty limit, two seconds will be assessed. At Regional events, local
methods for locating pylons may be used. The diagram provided herein
should help clarify situations in which penalties should and should not
be assessed.
7.9.2 Displaced or Downed Pylons on Course
A competitor encountering a downed or displaced pylon on course has
the option of continuing the run or stopping as soon as possible, and
pointing out the downed or displaced pylon to a course worker. If the
competitor stops, he/she must proceed per Section 7.4 and will then be
granted a rerun. However, if the competitor completes the run, the time
will stand. In the case in which a competitor is red flagged or stops for
a downed or displaced cone on the course, the competitor may continue slowly through the remainder of the course, or may exit the course
directly, and will be granted a rerun if appropriate. Failure to exit the
remainder of the course at an appropriate speed (generally 25-30 mph)
will result in a DNF for that run. It is important to clear the course in a
timely manner to ensure the event remains on schedule.
Reruns for displaced or downed cones after the timing finish line will
only be given at the discretion of the Chief Steward.
7.9.3 Course Deviation
A “DNF” or a time penalty, if so specified in the supplementary regulations, shall be charged for any uncorrected deviation from the course
for failing to directly follow the prescribed course route from the stage
line through the timing start line or for unnecessarily delaying the event.
A course deviation shall not be charged if any part of the car hits a
marker defining the limits of the course. A DNF is charged only if part
of the course is omitted. In returning to the course after an off-course
excursion, it is acceptable to drive a part of the course a second time.
No Penalty Assessed
Penalty Assessed
If the finish trip beam is broken while the front two (2) wheels of the
car are off-course, the run will be scored as a DNF. Additionally, if after
breaking the finish trip beam a driver causes the finish trip beam to be
broken again, stopping the timer for the following driver, the time for
the first driver will be scored as a DNF and the second driver may be
granted a rerun.
7.9.4 Range of Penalties
Any car or driver found to have competed illegally in an event will be
penalized. Penalties assessed by the Protest Committee may range
from written reprimand and/or time penalties to disqualification (Section
9.4.1).
7.9.5 Mechanical Did Not Finish
A Mechanical Did Not Finish (MDNF) will be charged to any competitor who completes their run with the physical assistance of another or
leaves the driver’s seat. This may be shown in the official results as a
DNF. A driver may leave the seat to restart a stalled kart without incurring this penalty.
7.10 OFFICIAL RESULTS
Official results shall by typed and printed by class and position in class
in order of best time, and must include (at least) the driver’s name (first
and last), hometown, car number, car make, model, year, class, tire
manufacturer, Region affiliation, designation of trophy winners, corrected time for each run, and penalty for each run (if any). (Event organizers are encouraged to also include the competitor’s sponsors’ names.)
The general outcome of protests and appeals at National Tour and the
National Championship events shall be included in the official results or
published in the official SCCA® publication. For example:
Car #3 HS-Protested for illegal suspension modification. Protest disallowed.
Car #18 AM-DSQ, did not report to impound. Car #6 BSP-DSQ, driver failed to report for required worker assignment.
Official results shall be mailed to the event competitors and the Solo®
National Office within two (2) weeks after the event. If an appeal has
been filed, preliminary results must be mailed within two (2) weeks only
to the Solo® National Office. Final official results must be mailed within
two (2) weeks of the decision of the Appeals Committee to the event
competitors and the Solo® National Office.
8. PROTESTS
While the right to protest in proper cases is undoubted, it should be remembered that Solo® events are sporting events, to be conducted in a
sporting spirit; that all events are organized and managed by amateurs
who cheerfully give their time and do their best, that the competitor may
expect some imperfections of the organizers and of his fellow comSection 7 — 57
petitors; and that, to a reasonable extent, these things are part of the
chances he takes in entering the competition.
8.1 WHO MAY PROTEST
The right to protest shall rest with any entrant, driver or official taking
part in the competition in question. Each may protest any decision, act,
or omission of the organizers, an official, entrant, driver, or other person
connected with the competition, which the protestor believes is in violation of the Solo® Rules, the Supplementary Regulations, or any conditions attached to the sanctioning of the event by SCCA® (hereafter in
this section collectively referred to as “the rules”). A protest against a
car is also a protest against its driver and entrant.
8.2 LODGING A PROTEST
A protest shall be made in writing, specifying which sections of the
Solo® Rules or other applicable rules are alleged to have been violated, and signed by one protesting entrant or driver or official. It shall
be delivered to the Chief Steward or to his designated representative,
or to the chairman of the Protest Committee (PC). If delivered to the
Chief Steward, it shall be promptly forwarded to the chairman of the PC.
8.2.1 Protest Fee
The protest shall be accompanied by a protest fee of $25 at National
Tour events and $80 at National Championship events. The fee will be
doubled for protests against cars (Section 8.3) that are filed after the
car is released from Impound on its first (1st) day of competition. The
protest fee is waived for protests filed in an official capacity by the Chief
Steward.
8.2.2 Time Limits
A. A protest against a competition vehicle shall be lodged before it is
released from Impound on its final day of competition.
B. A protest against the actions of a driver, entrant, or official during
class competition, including a protest against Timing and Scoring,
shall be lodged not later than 30 minutes after the class is released
from Impound on the day of the suspected violation of the rules.
C. A protest against the actions of a driver, entrant, or official outside of
class competition shall be lodged not later than 30 minutes after the
last class is released from Impound on the final day of competition.
D. A protest filed in an official capacity by the Chief Steward shall be
lodged not later than 30 minutes after the last class is released from
Impound on the final day of competition, except for a protest resulting from an Impound or Protest Committee inspection. Such protests
shall be lodged within a reasonable time after discovery of the suspected violation of the rules.
8.3 PROTESTS AGAINST CARS
Entrants or drivers taking part in a competition may protest a car in the
same competition and class as not conforming to the rules. The Chief
Steward may protest any car in the competition. The protestor may request that the car be disassembled, inspected, or any other test made,
provided he or she posts a cash bond with the PC sufficient to cover
the expense of access to documentation, disassembly, inspection and
reassembly. A protest may be reduced in scope but not added to at the
time the bond is set. Once a bond is posted, the stipulated inspections
shall be completed unless the protest is wholly or partially withdrawn
by the protestor. The PC shall apportion the costs incurred, including
reassembly, up to the point of withdrawal, provided no illegality has
been discovered.
8.3.1 Burden of Proof
The entrant of a protested vehicle has the burden of proving that the vehicle conforms to these rules by the required documentation according
to the class of the vehicle, and must present the required documentation to the PC at the time that the protest is heard, or else be disqualified.
If the required documentation does not include sufficient information on
a protested item or specification, the burden shifts to the protestor to
prove the equipment or specification illegal.
8.3.2 Impounding of Protested Cars
Protested vehicles held in Impound must remain there until one hour after announcement of the decision of the PC. If no appeal or intent to appeal has been filed by the end of that period, the car shall be released.
If an appeal or intent to appeal is filed, the Appeals Committee shall be
given the opportunity to inspect the vehicle before it is released. For
cars with multiple drivers, the car shall be released if needed for competition purposes under the supervision of the Chief Steward or their
designated representative.
8.3.3 Establishment of Bond
A. The bond shall be established by the PC after consulting separately
with the protestor and the protestee, and with the Chief Technical
Inspector and any other experts whose advice the PC believes shall
be useful.
B. Items covered by the bond may be priced individually, with consideration given to possible logical linking of some items. This cost schedule shall be set up prior to initiation of the inspection. The bond may
be awarded after teardown on a predetermined apportionment basis. Apportionment of the bond after the fact is not permitted, except
where the protestor has withdrawn all or part of the protest.
C. The bond shall be paid by cash, traveler’s check, or approved credit
card.
D. Where the circumstances warrant, the PC may require the protested
party to post bond or sign a repair order with a service establishment
to cover the costs of access to documentation, disassembly and inspection, in the event judgment goes against him or her. The bond
shall be established in the same manner as a protestor’s bond.
Section 8 — 59
8.3.4 Conduct of Inspection
The inspection and/or disassembly shall be conducted under the supervision of the PC. They shall determine which portions of the inspection
and/or disassembly, if any, may be observed, and by whom. The owner
or driver of a protested car, or his/her representative, will be allowed to
observe the inspection and/or disassembly but shall not interfere in any
way. The PC shall have authority to impose penalties upon finding any
additional illegal item(s) during an inspection.
8.3.5 Refusal to Allow Inspection
Refusal of an entrant or driver of a protested car to allow inspection
under the terms established by the PC shall result in immediate disqualification.
8.3.6 Disposition of Bond and Protest Fee
If the car conforms to the rules, the protestor shall forfeit the bond and
protest fee. After compliance with 8.3.6 the bond will be paid to the
protested party. The protest fee will be retained by SCCA®. If the car
does not conform to the rules, the entire protestor’s bond and protest
fee shall be returned and the protested party shall stand all expenses.
8.3.7 Time of Disbursement of Bond; Appeal Escrow
If an Intent to Appeal has been filed, the teardown bond and protest fee
shall be sent to the Solo® National Office to be held in escrow until the
time limit for appeal has passed, an appeal has been rejected (Section
10.5 - Decision to Hear Appeal), or an appeal has been finally decided
by SCCA®.
8.3.8 Preservation of Evidence
Any recorded evidence such as technical data or inspectors’ reports
or measurements shall be forwarded to the Solo® National Office. The
protest form with disposition of protest, and complete records from the
Protest Committee hearing, shall be forwarded to the Solo® National Office. A summary of protest findings will be provided to the event
Chief of Timing and Scoring for inclusion in the official event results.
The Chairman of PC shall accept any parts found illegal and tendered
by the owner for safekeeping pending appeal. The PC shall have the
authority to impound parts found illegal until the protest and appeals
process is complete.
8.3.9 Notifications
If a penalty is imposed as a result of personal misconduct or unsportsmanlike conduct, the PC chairman will notify the SEB as soon as possible. The SEB will notify the Vice President of Rally/Solo® as soon as
possible of the penalty, background information, and any appeals to the
NAC.
8.4 PROTEST COMMITTEE
The protest will be decided on the day of the event by a PC of at least
three members, within a reasonable time following completion of the
event. If the protest cannot be decided on the day of the event, the PC
must resolve it within one week. The delayed protest decision will be
mailed by certified mail, return receipt requested, to both parties of the
protest. The names of the committee members shall be specified in
the supplementary regulations or prominently posted on the day of the
event. The Chief Steward or Event Chairman shall not be members of
the Committee. For the National Championship event, a PC shall be
appointed by the SEB in advance of the event.
8.4.1 Duties
It is the function of the Protest Committee (PC) to adjudicate protested
violations of the SCCA® Solo® Rules in a fair, unbiased, and timely
manner. Members of the PC may also be drivers in the same event,
but will not perform any other duties than those of the PC. If a protest is
received in the same class as a PC member, or if a committee member
has some other personal interest in the class affected, he/she must
disqualify himself/herself from the protest ruling. This committee may
confer with the SEB members present on a protest where the input of
the SEB would be deemed necessary. For the National Championship
event, the PC may include the Divisional Solo® Stewards in attendance
at the event and/or others as the SEB deems necessary, with the exception of the PC Chairman who shall be appointed by the SEB.
8.5 HEARING OF THE PROTEST
The PC shall hear the protest as soon as practical after the protest is
lodged. All parties concerned shall be given adequate notice of the time
and location of the hearing. They shall be entitled to call witnesses, but
shall state their cases in person. In the absence of a party, judgment
may go by default. Each party or witness shall be heard separately or
in private. If judgment cannot be given immediately after the hearing, all
parties shall be informed of the time and method by which the decision
shall be conveyed. (All parties must stay until the end of the hearings.)
8.6 DISTRIBUTION OF AWARDS
A. Distribution of awards may commence after the period for receiving
protests has elapsed. When a protest which would affect distribution of awards has been lodged, distribution of awards for positions
which could be affected shall be withheld until the protest has been
settled. The PC, if it receives an intent to appeal their decision, shall
order awards which may be affected by the outcome of the appeal to
be withheld pending the decision of the National Appeals Committee
(NAC).
B. Pending the decision of the NAC, the results of the competition shall
be considered provisional.
8.7 JUDGMENT
All parties concerned shall be bound by the decision given, subject only
to appeal as provided in Section 10.
Section 8 — 61
8.8 REASONABLENESS
It is expected that protests shall be reasonable, logical, and based on
sound evidence, thus well-founded. A well-founded protest shall further
be defined as one upon which reasonable men or women may differ. A
protest may be well-founded even if not upheld.
8.8.1 Forfeiture of Protest Fee
If a protest is judged to be not well-founded, the protest fee shall be
forfeited.
8.8.2 Vexatious Or Bad Faith Protests
A protestor who has acted in bad faith or in a vexatious manner may be
penalized by the PC.
8.8.3 Return of Fee
The fee for a protest that is not upheld but is determined by the PC to
be well founded may be returned to the protesting party upon the decision of the PC.
9. PENALTIES
All participants shall be subject to control by SCCA®, the organizing
SCCA® Region or other organizers, and all appointed officials of the
event. This Section provides the penalties for violation of the Solo®
Rules and the Supplementary Regulations.
9.1 BREACH OF THE RULES
In addition to any other offenses or violations of specific rules each of
the following shall be deemed a breach of the Solo® Rules.
A. Bribery or attempt to bribe anyone connected with the event; and the
solicitation of, acceptance of, or offer to accept, a bribe.
B. Any fraudulent proceeding or act prejudicial to the interests of the
SCCA® or of car competition generally.
C. Reckless or dangerous driving, either on course or in the pits and
paddock.

G. Physical violence toward any other participant or spectator at the
event.
9.2 WHO MAY BE PENALIZED
Any organizer, entrant, driver, crew member, official, worker or guest of
the above, or SCCA® member may be penalized. If a car is found to be
in violation of a rule and the protest is upheld, the penalty imposed on
the protested driver will be applied equally to all drivers of the car in that
category even if they were not specifically named in the protest.
9.3 HEARING
No penalty shall be imposed by the PC except after a hearing that follows the procedures set out in Section 8.
9.4 IMPOSITION OF PENALTIES

the finishing order shall be advanced.
Section 9 — 63
9.7 PUBLICATION
The SCCA® shall have the right to publicize a notice that any person,
organization, or car has been penalized and the reasons for the action.
Any person or organization referred to in the notice shall have no right
of action against SCCA® or against any person for publishing such
notice or for its contents.
10. APPEALS
10.1 RIGHT TO APPEAL
Any person, entrant or organization named as a party to a protest in
any SCCA® Solo® event shall have the right to appeal to the National
Appeals Committee (NAC) any decision or penalty imposed. In addition
the Chief Steward of the event shall have the right to appeal any decision or penalty imposed.
10.2 INTENT TO APPEAL
For a protest decided on the day of the event, a written intent to appeal
or a formal appeal accompanied by the appropriate appeal fee shall be
submitted to the Chief Steward or Appeals Committee (AC) within one
hour after the announcement of a decision on a protest, or the right to
appeal is forfeited. For delayed protest decisions, an appeal and appropriate appeal fee must be received by the Solo® National Office within
seven (7) calendar days of notification of the protest decision. The time
period starts on the date of the return receipt of the certified mail notification of protest decision.
10.3 TAKING AN APPEAL
An appeal permitted hereunder shall be taken by filing a written appeal
with the Solo® National Office. The notice of appeal shall specify the
party or parties making the appeal; shall designate the decision or portion thereof appealed from; shall explain the reason or reasons why the
appeal should be heard; and if applicable, which part(s) of the Solo®
Rules are considered to have been enforced in a manner that was not
fair or equitable to the appellant; and shall be received at the Solo®
National Office within ten (10) days after submission of the Intent to
Appeal, and shall include the appropriate appeal fee of $50 payable
to SCCA®, Inc. A minimum of $25 of the appeal fee may be retained
to defray expense of hearing the appeal by the SCCA® on all appeals
that are filed. An appeal properly taken hereunder may be withdrawn,
without penalty, by written notice to the SCCA®, Inc. prior to the acceptance of the appeal by the NAC. Under Section 10.6, the AC, in their
judgment, may decide that the penalty or other decision of the PC or
other committee appealed from should be nullified, mitigated, affirmed,
increased or a different penalty imposed, but it shall not order a competition to be rerun.
10.4 COMPOSITION OF THE NATIONAL APPEALS COMMITTEE
The purpose of the NAC is to render a final decision in any appeal
permitted to be taken under this section. The NAC will be appointed
by the SEB. Members who competed in the same event and class addressed in an appeal, or who have other personal interest in the appeal,
must disqualify themselves from participating in the appeal. If fewer
than three members are available, then additional people to reach a
total of three may be appointed by the SEB to address that appeal. It
is the intent of these provisions to provide for resolution of differences
before a Committee composed of individuals with individual and collective expertise in Solo® matters.
10.5 DECISION TO HEAR
The NAC will make the final decision whether or not the appeal is well
founded and should be heard, and whether the appeal fee should be
returned or forfeited. Appeals not received within the specified time limit
will not be heard. Said decision shall be final, binding, and not subject
to appeal. In reaching this decision, they may review the findings of and
documentation provided to the PC, the written appeal, and any other
material they deem pertinent. The officials designated herein shall use
every effort to make their final decision within seven days of the receipt
for the written appeal.
10.6 CONVENING THE APPEALS COMMITTEE
The NAC will determine if it shall hear the appeal or if it will be heard
by another AC, which they will appoint. No member of either committee
shall have been directly or indirectly interested or involved in the matters under consideration. The Chairman of either committee shall not
be a member of the appellant’s Region of Record.
10.6.1 Hearing The Appeal / National Appeals Committee
The NAC will use its best efforts to hear an appeal within a reasonable
length of time from notice to all parties. The method of hearing the appeal will be determined by the NAC.
10.6.2 Appointed Appeals Committee
The appointed AC shall be convened in the Division in which the event
was held, with due consideration given to the geographical convenience of the parties to the appeal and the members of the committee.
The appointment of the committee and written notice to the appellant(s)
shall occur within seven days of the decision to hear the appeal. The
Chairman of the AC will notify the Chairman of the PC of the appeal.
10.6.3 Hearing The Appeal
The appointed AC shall use its best efforts to convene and hear the
appeal no earlier than one (1) week from notice to the parties and no
later than four weeks from said notice. At a hearing all parties concerned shall be entitled to call witnesses and present, within reason,
other evidence of their choice. They may present their case personally,
be represented by an advocate, or may submit the case to the committee on documents without personal appearance. The AC may hear
Section 10 — 65
such evidence in such manner as it deems appropriate, relevant, and
necessary under the circumstances.
10.7 JUDGMENT OF THE APPEALS COMMITTEE
After considering all material they deem relevant, the AC shall meet
privately, reach its decision and prepare a written opinion. It may decide
that the penalty or other decision of the PC be nullified, mitigated, affirmed, increased or a different penalty imposed, but shall not order a
competition to be re-run. The committee shall order the return or forfeiture of appeal fees. The committee shall direct the disposition of protest
fees and teardown bonds, if any, in those cases where the PC decision
is nullified.
10.8 PUBLICATION AND EFFECT OF DECISION
The SCCA® will distribute all final NAC decisions, including the names
of all parties concerned. Persons, entrants or organizations referred to
in each said decision shall have no right or action against SCCA® or
any person publishing such notice, and agree that said decision shall
be final and binding. SCCA® will use its best efforts to publish said
final decisions as soon as possible after finalization. A copy of the final
decision of the AC shall be sent to all parties of the appeal as soon as
possible after the decision becomes final. Any penalty imposed by the
AC shall be effective immediately as stated in its decision. If a penalty
is imposed as a result of personal misconduct or unsportsmanlike conduct, the NAC will notify the SEB as soon as possible. The SEB will
notify the Vice President of Rally/Solo® as soon as possible.
10.9 BAD FAITH APPEALS
If the committee determines that the appellant has acted in bad faith or
in a vexatious manner, it may deem such conduct a breach of the Solo®
Rules and impose an additional penalty for said breach.
11. AWARDS
A. Awards shall be given to the highest placed drivers in each class on
the following basis unless otherwise provided by supplementary regulations. One (1) award for one to three (1-3) entrants in a class; two
(2) awards for four to six (4-6) entrants in a class; three (3) awards
for seven to nine (7-9) entrants in a class; one (1) additional award
for every four (4) additional entrants or fraction thereof (e.g., six (6)
awards for 18 entrants).
B. At the Solo® Nationals, a National Championship award will be given
when a competitor competes in a National Championship eligible
class which has three (3) or more participants.
12. AUTOMOBILE DEFINITIONS
The following definitions shall apply to these Rules regardless of any
other definitions or interpretations.
12.1 AUTOMOBILE (CAR)
An automobile or car is a self-propelled land vehicle, running on at least
four (4) wheels, not in a line, which must be in contact with the ground
when at rest.
12.2 SEDAN
A sedan is a car capable of transporting four (4) or more average-size
adults in normal seating positions.
12.3 MODEL
A group of cars of a given make which have virtually identical bodies and chassis but are readily distinguished from other models of the
same make by virtue of a major difference in body appearance and/
or chassis design. The names by which the manufacturer designates
these groups have no bearing on this definition even though two (2)
groups may be designated identically.
12.4 STANDARD PART
An item of standard or optional equipment that could have been ordered with the car, installed on the factory production line, and delivered
through a dealer in the United States. Port-installed options provided
by the factory are considered to be the same as those installed on the
factory production line. Dealer-installed options or deletions (except as
required by factory directives), no matter how common or what their
origin, are not included in this definition. This definition does not allow
the updating or backdating of parts.
12.5 TRACK
The distance between the centerlines of the wheels as competed without driver, measured as follows: From centerline to centerline of wheels.
Alternatively, it may be measured from the inside of one wheel at the
hub centerline height to the outside of the other wheel, then conversely
from the outside of the first wheel at hub centerline to the inside of the
second wheel. The two dimensions obtained are to be added together
and divided by two (2) to obtain the average. Measurements are to be
taken at both front and rear of the wheels and averaged to compensate
for toe in/out. Wheel rim width shall be measured at the base of the
bead seat.
12.6 OPEN AND CLOSED CARS
A. An open car is a convertible (with or without a full windshield), a car
with a retractable hardtop, a targa-top-type car with less than a full
windshield, or a T-top-type car with less than a full windshield.
B. A closed car is one with a full roof, a targa top-type car with a full
windshield, a T-top-type car with a full windshield, or a convertible
with a full windshield and a standard (as defined herein) hardtop
which has been bolted securely in place.
Section 12 — 67
12.7 FLOOR PAN
The floor pan is defined to include all surfaces which would support the
driver’s or passenger’s feet, body, or seat in the original car, extending
laterally from (but not including) door sill to door sill and longitudinally
from (but not including) front bulkhead to rear bulkhead.
12.8 DRIVER/PASSENGER COMPARTMENT
The driver/passenger compartment is the interior area of the car in
which original driver control devices and all original seating were/are
located.
12.9 WING AREA COMPUTATION
The area of a wing element shall be computed by multiplying the maximum chord (straight line distance from leading edge to trailing edge)
by the maximum span (width). Curvature of the element (camber) and
angle of attack when mounted on the vehicle will not affect the area
measurement. The area for multiple-element wings will be the sum of
the individual areas of each of the elements.
12.10 CANARD
A three-dimensional (3D) attachment to the front fascia with air passing
over the top and bottom surfaces, which is intended to provide aerodynamic downforce to the front of the vehicle. Unlike a wing, one (1) edge
must be flush to the attachment surface. No portion of a canard may
extend vertically above the front fascia/bodywork.
12.11 ACTIVE/REACTIVE SUSPENSION
An active/reactive suspension is a system in which the weight of the car
is carried or assisted by an actively adjustable/programmable medium
such as a hydraulic or pneumatic ram.
12.12 TRACTION/STABILITY CONTROL
A system that adjusts engine power, braking force, or torque distribution
when wheelspin, understeer, or oversteer is detected or predicted. Conventional limited slip differentials (e.g. viscous, passive clutch, helical/
worm gear, locker) are explicitly excluded, but “active” differentials and
their controllers are included.
12.13 MID-ENGINE
A mid-engine configuration is defined as one in which the engine is located behind the passenger compartment and in front of the rear axle.
12.14 BLOW-OFF VALVE (BOV) / POP-OFF VALVE (POV)
A device intended to limit maximum boost pressure in the engine inlet
system by opening to vent the inlet system to the outside atmosphere
when a preset boost value is reached.
12.15 COMPRESSOR BYPASS VALVE (CBV)
A device intended to allow a supercharger or turbocharger’s compressor output to recirculate back to the supercharger or turbocharger inlet
when the throttle plate is closed. The purpose of this recirculation is to
reduce boost lag when the throttle plate is reopened. A CBV is referenced to intake manifold vacuum and opens when manifold vacuum
exceeds a preset value. It is closed under boost. CBVs installed by
OEMs operate as described above. Some aftermarket CBVs vent to the
atmosphere, and are marketed as Blow Off Valves or Pop Off Valves,
although their operation is otherwise identical to the OEM CBVs.
12.16 SOLID REAR AXLE
A dependent rear suspension system in which the wheels are mounted
at each end of a solid, or undivided, axle or axle housing; includes live
axles and beam axles as found on both RWD and FWD cars.
12.17 VARIABLE VALVE TIMING (VVT)
VVT is any system that dynamically alters the timing of valve events
while engine is operating.
12.18 STRUT BAR
A transverse member connecting the upper or lower suspension mounting points at the front or rear of the car. Strut bars may be mounted only
transversely across the car from upper left to upper right suspension
mounting point and from lower left to lower right suspension mounting
point. A two-point strut bar fastens only at the left and right suspension
pointing points. A triangulated strut bar has a third area of attachment
at the chassis (e.g., at the firewall/bulkhead). All connections to the vehicle must be bolted. No connection point to the chassis can be welded.

13. STOCK CATEGORY
Cars running in Stock Category must have been series produced with
normal road touring equipment capable of being licensed for normal
road use in the United States, and normally sold and delivered through
the manufacturer’s retail sales outlets in the United States. Car models
not specifically listed in any Stock Category class must have been produced, and must meet the above requirements and been sold through
normal U.S. dealerships, in quantities of at least 1,000 in a 12-month
period in order to be eligible for the Stock Category. A Canadian-market
vehicle is eligible for Stock category if it is identical to the US-market
counterpart except for comfort and convenience modifications as allowed per 13.2.A.
A car will remain eligible for National Tour and National Championship
events through the end of the 30th calendar year after the manufacturer-designated model year of the car. This eligibility limitation applies
only to the Stock classes.
Except for modifications authorized below, Stock Category cars must
be run as specified by the factory with only standard equipment as defined by these Rules. This requirement refers not just to individual parts,
but to combinations thereof which would have been ordered together
on a specific car. Any other modifications or equipment will place the car
in Street Touring, Street Prepared, Street Modified, Prepared or Modified Categories as appropriate. Configurations involving damaged parts
(e.g., blown fuses) are not typically authorized by the manufacturer and
hence are not allowed.
Option package conversions may be performed between specific vehicles of a particular make and model, but only between configurations
from within a particular model year. Such conversions must be totally
complete and the resultant car must meet all requirements of this Section. These requirements are not met by simply pulling a fuse to disable
a feature which distinguishes one model from another.
Alternate parts listed in a factory parts manual are not authorized unless their use is specifically referenced in the factory service manual or
in a service bulletin for the specific model.
See Sections 3.8 and 8.3.1 for documentation requirements.
Alternate components which are normally expendable and considered
replacement parts (e.g., engine and wheel bearings, seals, gaskets,
filters, belts, bolts, bulbs, batteries, brake rotors, clutch discs, pressure
plates, suspension bushings, drivetrain mounts, fenders, trim pieces,
etc.) may be used provided they are essentially identical to the standard
parts (e.g. have the same type, size, hardness, weight, material etc.),
are used in the same location, and provide no performance benefit. The
allowance for use of such replacements does not include camshafts,
differential covers, or ring-and-pinion sets, nor does it authorize the use
of piston rings having different configurations (e.g. “Total Seal”) from
those of the original.
13. Stock Category — 71
Hardware items (nuts, bolts, etc.) may be replaced by similar items of
unrestricted origin. Safety wire, threadlocker compounds, and locking
nuts are permitted. These allowances are strictly to allow components
to be replaced from alternate sources other than the original manufacturer. They should not be construed as an allowance to replace components with those which could be considered a ”higher performance”
alternative. Parts available as replacements through the dealers parts
department, the factory, or any other source which do not meet standard part specifications (e.g., hardness, size, etc.) are non-compliant
in Stock Category, except as specifically provided elsewhere in these
rules.
Cars listed as eligible in and prepared to the current national Showroom
Stock Club Racing rules are permitted to compete in their respective
Solo Stock Classes. This does not include Showroom Stock cars with
installations of post-factory “performance packages” otherwise known
as “trunk kits.” Neither Showroom Stock nor Solo Stock cars are permitted to interchange preparation rules. Showroom Stock cars may use
tires which are eligible under current SS rules, even if they are not eligible in Stock.
Specific vehicle classifications are located in Appendix A of these rules.
13.1 AUTHORIZED MODIFICATIONS
If a modification is not specifically authorized in this or previous sections
of these Rules, it is not allowed.
The addition of small holes for attachment hardware for authorized
modifications is implicit (e.g., holes for fasteners to mount additional
gauges, holes for brackets to mount shock absorber remote reservoirs,
etc.). However, these holes may serve no other purpose.
All repairs must comply with factory-authorized methods and procedures.
It is not permitted to use non-compliant parts even if they have been set
to Stock specifications.
Refer to Appendix F for past clarifications of these rules.
13.2 BODYWORK
A. Accessories, gauges, indicators, lights and other appearance, comfort and convenience modifications which have no effect on performance and/or handling and do not materially reduce the weight of
the car are permitted. This does not allow driver’s seat substitutions,
or the removal of “tow hooks”, a.k.a. “tie-down loops”. Delayed shutdown devices such as the “Turbo Timer”, which perform no function
while the car is in motion, are permitted. This does permit the installation of an additional mirror (e.g. a “Wink”), but does not allow the
removal of the original mirror. “Grounding kits” specifically designed
to support sound systems are permitted but may serve no other purpose.
B. Data acquisition systems (including video cameras) and the accompanying sensors are allowed but may serve no other purpose during
the run than real-time display and data recording.
C. Hood straps or fasteners may be added.
D. Any fuel tank cap may be used.
E. Windshields may be folded (but not removed) provided the required
mechanism is standard equipment.
F. Alternate steering wheels are allowed, provided the outside diameter
is not changed by more than one inch from the standard size. Steering wheels with an integral airbag may not be changed.
G. Alternate shift knobs are allowed.
H. Spare tires, tools and jacks may be removed. Any fastening hardware and/or other pieces that can no longer be firmly secured in the
absence of the spare tire may be removed if necessary to ensure
compliance with 3.3.3.B.1.
I. Roll Bars and Roll Cages
1. Roll bars may be added. Roll bars may be welded in. Standard
rollover hoops and covers may be removed if the resulting installation meets Appendix C, A. Basic Design Considerations. The
total weight of components added must not be less than that of
components removed.
2. Roll cages may be added. It is strongly recommended that roll
cages be constructed according to the Club Racing GCR, though
they must be bolted (not welded) into the automobile and be contained within the driver/passenger compartment. A roll cage has
more than four attachment points to the body or frame, or has
bracing both fore and aft of the main hoop.
J. Driver restraints as outlined in Section 3.3.1 are allowed. Seats may
not be cut to allow for the installation of alternate seat belts or harnesses. Passive restraint systems may not be removed. A horizontal
“harness bar” may be used as part of the installation hardware for
allowed driver restraints provided it has no more than two attachment points to the chassis and is bolted at those locations. A ‘C’-type
harness bar may also be used. It may have four bolted attachment
points to the chassis (two primary, and two supporting connections to
resist rotation). Truss-type harness bars are not allowed.
K. Cars may add one rear trailer hitch. The resulting weight addition is
allowed. The hitch may serve no other purpose. Factory tie downs
and cosmetic pieces (e.g. diffusers) may be modified or removed to
facilitate hitch installation. Complete or partial removal of the hitch is
allowed for competition, provided it does not result in a reduction in
weight compared to the unmodified standard configuration.
L. Tow bar brackets may be installed but may serve no other purpose.
M. Any item that cannot be held permanently in place by factory-installed fasteners may be removed.
13.3 TIRES
Any tire which is OE on a car eligible for Stock Category may be used.
Non-OE tires must meet the following requirements to be eligible for
use in Stock category:
A. The tire must not appear on the following list, which may be altered
at any time by the SEB upon notification of membership.
No tire models are currently listed.
B. No tire models will be approved for competition during the rest of
the year after April 30 of each calendar year. Each eligible tire model
must meet all requirements of Section 13.3 by April 30, and must
continue to meet them thereafter. A tire model will normally be determined by the designation in the Tire Guide.
However, any of the following changes or similar changes (as determined by the SEB) will also be considered to represent a new model for eligibility purposes, even if the designation does not change:
change of tread pattern at either full or partial tread depth; characterization by the manufacturer or distributor of a tire as “new” after
April 30.
A tire model which was previously allowed by these rules continues
to be legal until specifically disallowed. This follows years of precedence on eligibility for discontinued tire models.
If a manufacturer reintroduces a tire model which was previously
discontinued, that tire will be considered a new model. Therefore,
it will have to meet the rules specified in Section 13.3 including the
April 30 introduction date.
C. The model of tire must be listed in a current or previous two years of
the “Tire Guide” and “Tread Design Guide” or otherwise be approved
by the SEB. The tire model must have Department of Transportation
(DOT) approval.
D. Within each tire model, the sizes which are available must be equally
available to all competitors. Tire model variations differing from standard specification, delivered only on a limited basis, or only to selected competitors, may not be used.
E. No non-DOT racing tire or recap (on any casing) may be used. Siping or re-grooving of tires is not permitted.
F. Each tire model must be sold in at least four rim diameters with a total
of at least six sizes.
G. Tire must fit the allowable wheels and fender wells without modification.
H. Each tire must have non-zero measurable tread depth (i.e., points
where it is possible to obtain positive measurement values) as de74 — 2012 SCCA® National Solo® Rules
scribed in Section 3.3.3.B. Tires may not have cord visible at any
time during competition.
13.4 WHEELS
Any type wheel may be used provided it complies with the following: it
is the same width and diameter as standard, and as installed (including wheel spacers if applicable) it does not have an offset more than
+/- 0.25 inch from a standard wheel for the car. The resultant change in
track dimensions is allowed.
Wheel spacers are permitted, provided the resultant combination complies with the offset requirements of this section. Wheel studs, lug nuts,
and/or bolt length may be changed.
Vehicles equipped with rims having metric specifications may use alternate rims as determined by using the following procedure:
Diameter: converting the metric measurement to inches and using
the nearest smaller inch diameter rim.
Width: converting the metric measurement to inches and using the
nearest smaller 1/2-inch width rim. Offset and track must still comply with the requirements of this section.
13.5 SHOCK ABSORBERS
A. The make of shock absorbers, struts, and strut housings may be
substituted providing that the number, type (e.g., tube, lever, etc.),
system of attachment and attachment points are not altered, except
as noted below. The interchange of gas and hydraulic shocks absorbers is permitted. The following restrictions apply:
1. No more than two separate external shock damping adjustment
controls are allowed. This permits the use of shocks which originally came with more than two external adjustments, which have
been converted to double-adjustables, only if the additional adjustment controls have been permanently disabled (e.g. via welding, epoxying, grinding off). Gas pressure adjustment is not considered a damping adjustment.
2. Suspension geometry and alignment capability, not including ride
height, may not be altered by the substitution of alternate shock
absorbers. Aftermarket strut housings are allowed provided that
they meet the Stock category shock requirements defined herein,
i.e. that no suspension geometry changes result. This includes the
position of the steering arm attachment point in the case of struts
with integrated steering arms.
3. Adjustable spring perches are allowed, but the spring loadbearing
surface must be in the same location relative to the shock mounting points as on the standard part. Shims may be used to achieve
compliance.
4. The fully extended length must be within plus or minus one inch of
the dimension of the standard part.
5. Electronically controlled shocks may not be used on vehicles not
originally equipped with such units. Vehicles originally equipped
with electronically controlled shocks may use the standard parts
or non-electronically controlled alternative shocks subject to all
the requirements of 13.5. Non-standard electronically-controlled
shocks are not allowed.
B. The mounting hardware shall be of the original type. The use of
any shock absorber bushing material, including metal, is permitted.
Pressed or bonded bushings may be removed from standard parts
to facilitate the use of alternate bushings which fit in the original location without alterations to the part. This does not permit the use of
an offset shock bushing. A shock absorber bushing may be implemented as a spherical bearing. The bushing attaching the end of a
strut to the body or frame on a strut type suspension is a suspension
bushing, not a shock bushing.
For cars with a bayonet/shaft-type upper shock mount, this allowance
permits the removal of the shock bushing from the upper mounting
plate (e.g. via drilling, cutting, burning out the bushing) and replacing
it with another bushing. This also includes shock bushings located in
control arms, etc. This does not allow other modifications to the plate
itself or use of an alternate plate.
C. To facilitate the installation of commonly available aftermarket shock
absorbers, struts, or strut inserts whose shaft size is larger than the
center hole of an upper shock mount assembly, that hole may be enlarged by the minimum necessary to accommodate the shock shaft
size, provided the following restrictions are met:
(1) the enlarged hole must remain concentric with the original configuration;
(2) the enlargement of the hole does not require modification of a
bearing (as opposed to a washer, sleeve, or plate);
(3) neither the hole enlargement nor the location of the shock shaft
changes any alignment parameter. Provided these constraints are
met, this permits enlarging of the center hole in an upper shock
mount with an integrated rubber bushing, where the bushing is
integral to the mount and bonded to the plate and the mount is
provided by the OEM as an assembly. This includes drilling out
and/or removal of the metal sleeve.
D. A suspension bump stop is considered to be performing the function
of a spring. Therefore, the compressed length of the shock at the
initial point of contact with the bump stop may not be increased from
the standard part, although the bump stop may be shortened for the
purpose of installing non-standard shocks. Bump stops installed externally and concentric with the shaft of a shock may be drilled out to
fit a larger diameter shock shaft. Bump stops may be substituted for
the purposes of installing non-standard shocks.
E. A hole may be added through the bodywork to route the reservoir
and hose to a remote mounting location. Such holes may serve no
other purpose.
F. A hole may be added to an interior body panel to provide access
to the adjustment mechanism on an allowed adjustable shock absorber. The hole may serve no other purpose, and may not be added
through either the exterior bodywork or a strut bar. Interior panels
are defined to be those pieces which cover the interior of the vehicle
(including the trunk area) and are accessible from inside the vehicle.
They do not include structural panels, such as wheel wells or inner
fenders, which may also be accessible from inside the car but which
actually form part of the body of the vehicle.
13.6 BRAKES
A. The make and material of brake linings may be changed.
B. Substitution of clutch and brake hydraulic lines with solid metal or
braided metal is allowed on all cars manufactured before model year
1992.
C. Alternate brake bleeder fittings, such as “Speedbleeders,” are permitted. They may serve no other purpose.
13.7 ANTI-ROLL (SWAY) BARS
A. Substitution, addition, or removal of a single anti-roll bar and supporting hardware (brackets, endlinks, bushings, etc.) is permitted. The
use of any bushing material is permitted. A bushing may be implemented as a bearing.
B. Substitution, addition, or removal of anti-roll bars may serve no other
purpose than that of an anti-roll bar.
C. No modification to the body, frame, or other components to accommodate anti-roll bar addition or substitution is allowed except for the
drilling of holes for mounting bolts. Non-standard lateral members
which connect between the brackets for the bar are not permitted.
13.8 SUSPENSION
A. Standard, as defined herein, suspension springs must be used. They
may not be cut, shortened, or collapsed. Cars with swing axle suspension may be lowered sufficiently to achieve no more than two
degrees of negative camber at rest and may use a camber compensator. Spring perches may not vary from the OE shape within the
working part of the perch.
B. Both the front and rear suspension may be adjusted through their
designed range of adjustment by use of factory adjustment arrangements or by taking advantage of inherent manufacturing tolerances.
This encompasses both alignment and ride height parameters if such
adjustments are provided by the stock components and specified by
the factory as normal methods of adjustment. However, no suspension part may be modified for the purpose of adjustment unless such
modification is specifically authorized by the factory shop manual for
non-competition purposes.
C. Suspension bushings, including but not limited to those which carry
the weight of the vehicle and determine ride height, may not be replaced with bushings of a different material or dimension.
D. Replacement control arms for vehicles having integral bushing/arm
assemblies must be standard factory parts as per Sections 12.4 and
13.0.
E. If offered by the manufacturer for a particular model and year, the
use of shims, special bolts, removal of material to enlarge mounting
holes, and similar methods are allowed and the resulting alignment
settings are permitted even if outside the normal specification or
range of specifications recommended by the manufacturer. If enlarging mounting holes is specifically authorized but no material removal
limits are specified, material removal is restricted to the amount necessary to achieve the maximum factory alignment specification.
13.9 ELECTRICAL SYSTEM
A. The make of spark plugs, points, ignition coil and high tension wires
is unrestricted including spark plug wires having an in-line capacitor.
Substitution or addition of ignition coil mounting brackets is permitted, provided they affix to the original standard location and serve no
other purpose. (Modification of the distributor cap for the purpose of
installing allowed non-standard components is not permitted.)
B. On cars made prior to January 1, 1968, any ignition system using a
standard distributor without modification may be used.
C. Ignition settings may not be adjusted outside factory specifications.
D. No changes are permitted to electronic engine management systems or their programming.
E. Additional battery hold-down hardware may be added to supplement
the standard equipment in order to meet 3.3.3.B.15. It may serve no
other purpose.
13.10 ENGINE AND DRIVE TRAIN
A. The engine air filter element may be removed or replaced provided
the air flow path remains as originally designed (i.e., no additional
openings). No other components of the air induction system may be
removed, replaced, or modified.
B. Engines may be rebored to the manufacturer’s first standard overbore, not to exceed 0.020”. Sleeving is allowed to repair to the standard bore. Only OE-type standard or first overbore pistons of the
same configuration and of the same or greater weights are permitted. No interchange between cast and forged pistons is allowed.
C. Rotating and reciprocating parts may not be balanced.
D. Port matching is not allowed.
E. Any part of the exhaust system beyond (downstream from) the header/manifold or catalytic converter, if so equipped, may be substituted
or removed provided the system meets the requirements of 3.5 and
3.3.3.B.15. Stainless steel heat exchangers are permitted only if the
physical dimensions and configuration remain unchanged.
Modifications of any type, including additions to or removal of, the
catalytic converters, thermal reactors, or any other pollution control
devices in the exhaust system are not allowed and the system must
be operable. Replacement catalytic converters must be OE if the
vehicle has not exceeded the warranty period as mandated by the
EPA. Converters must be of the same type and size and used in the
same location as the original equipment converter(s). This does not
allow for a high performance unit. If the vehicle has exceeded the
warranty period, replacement catalytic converters must be OE-type
as per Section 13.0.
Exhaust hangers which are bolted or welded on the car are considered part of the body and may not be changed or removed.
F. Any oil filter may be added if not originally equipped. Canister-type
oil filters may be replaced with a spin-on type filter using a minimum
amount of hardware and connecting lines.
G. The installation of water expansion tanks is allowed. The installation
of oil catch tanks is allowed provided the function of the PCV system
is not altered.
H. A scattershield may be added. This does not permit bell housing
substitutions.
I. Thermostats may be added or substituted. A thermostat is a device
which controls the passage of water.
J. Silicone replacement hoses are permitted as alternate components
provided they meet the requirements of Section 13.0 with regard to
size, shape, location, and performance equivalence. Replacement
induction system air intake hoses must also match the standard part
in stiffness, contour, and internal wall texture.
K. A device for locking out reverse gear may be used.
L. Limited-slip differential, transmission and differential ratios, clutch
mechanisms and carburetion, fuel injection or supercharger induction systems must be standard as herein defined.
M. Any oil or grease, including synthetic, is permitted.
N. Valve seats and guides in older engines originally designed for leaded fuel may be only substituted with alternate components if the dimensions are the same as those of the standard components.
O. Electronic traction and/or stability control systems may be turned off
or disabled, as long as this does not require connection to an external system, removal of any part, or the substitution or modification
of any part.

14. STREET TOURING CATEGORY
The Street Touring category of vehicle modifications is meant to fit between the current Stock and Street Prepared categories. This category
provides a natural competition outlet for auto enthusiasts using affordable sports cars and sedans equipped with common suspension and
engine modifications compatible with street use.
Under the provisions of Section 1.1 of these rules, Regions are free
to allow any other version of the ST concept which meets their local
needs. In particular, some leeway in the area of bodywork allowances
(e.g., wings/spoilers beyond those allowed in 14.2.F) is encouraged at
Regional Solo® events.
See Sections 3.8 and 8.3 for documentation requirements.
All Solo® Rules Stock Category allowances, plus all allowances contained in 14.1 through 14.10.
14.2 BODYWORK
A. Pedal cover kits and other interior cosmetic accessories may be
added. “Dress-up” items such as chrome dipsticks and non-standard
filler caps are permitted, provided they serve no other purpose.
B. The driver and front passenger seats may be replaced, with the following restrictions: The seating surface must be fully upholstered.
The top of the seat, or an attached headrest, may not be below the
center of the driver’s head. The seat, including mounting hardware,
must weigh at least 25 pounds and must be attached using the OE
body mounting holes/studs. Additional mounting points may be added.
C. Factory rub strips, emblems, mud flaps, bolt-on front valance lips/
spoilers, and fog lights (except those integral to a headlight or turn
signal) may be removed. Rear wings may be removed so long as the
vehicle retains any federally-mandated third brake light.
D. Alternate steering wheels are allowed except that steering wheels
with an integral airbag may not be changed.
E. Fenders may not be cut or flared but the inside lip may be rolled to
gain additional tire clearance. (The outer fender contour may not be
changed.) Plastic and rubber wheel well splash shields may be modified for tire clearance and to accommodate a rolled inside fender lip.
The modifications may serve no other purpose (e.g. air intake, brake
ducts, etc). No other changes to the stock fenders or wheel wells are
permitted.
F. Addition of spoilers, splitters, rear wings, bumper covers, valances,
side skirts, and non-functional sccops/vents is allowed provided that
either:
1. It is a production part which is standard or optional equipment of a
US model of the vehicle.
14. Street Touring® Category — 81
2. It is listed in the vehicle manufacturer’s US accessory catalog
for that vehicle for normal highway use. This does not allow for
parts sold through a manufacturer’s performance catalog (e.g.,
Ford Racing, HPD, MazdaSpeed, Mopar Performance, Mugen,
NISMO, SPT, TRD, etc).
Parts must be installed as directed by the manufacturer. Exact replicas (including weight) from alternate sources are also permitted.
G. Strut bars (per Section 12) are permitted with all types of suspension, subject to the following constraints:
1. a two-point strut bar may be added, removed, modified, or substituted, but only with another two-point strut bar.
2. A triangulated (3-point) strut bar may be removed, modified, or
substituted; substitution may be with either a triangulated or a twopoint strut bar. The connection to the chassis (i.e., firewall, bulkhead, etc) must be in the standard location.
3. Lower suspension braces must be attached to the lower suspension pickup point locations on the chassis within 2 inches (2”, 50.8
mm) in any direction of the actual suspension attachment to the
chassis.
4. Except for standard parts, no connections to other components
are permitted.
Additional holes may be drilled for mounting bolts. Only bolt-on attachment is permitted. Interior trim panels may be modified to allow
installation of strut bars. Holes or slots may be no larger than necessary and may serve no other purpose. This does not permit any
modifications to the frame or unibody beyond the allowed mounting
holes.
H. Longitudinal (fore-aft) subframe connectors (“SFCs”) are permitted
with the following restrictions:
1. They must only connect previously unconnected boxed frame rails
on unibody vehicles.
2. Each SFC must attach at no more than three points on the unibody (e.g. front, rear, and one point in between such as a seat
mount brace or rocker box brace).
3. SFCs must be bolted in place and not welded.
4. No cutting of OE subframes or floorpan stampings is permitted.
Drilling is permitted for mounting bolts only.
5. No cross-car/lateral/triangulated connections directly between the
driver’s side and passenger’s side SFCs are permitted. Connections to OE components such as tunnel braces or closure panels
via bolts are allowed and count as the third point of attachment.
No alteration to the OE components is permitted.
6. SFCs may not be used to attach other components (including but
not limited to torque arm front mounts or driveshaft loops) and
may serve no other purpose.
14.3 TIRES
Tires must meet the eligibility requirements of the Stock category with
the following additional restrictions:
A. Tires must be mass-produced standard production tires designed
for normal highway use on passenger cars. Low volume and/or specialty tires will be specifically excluded below.
B. Tires may have section widths up to and including the following:
STF, STC, STS, STR (AWD) – 225 mm
STX (AWD), STU (AWD) – 245 mm
STR (2WD) – 255 mm
STX (2WD) – 265 mm
STU (2WD) – 285 mm
C. Tires must have a minimum UTQG treadwear rating of 140 and a
minimum molded tread depth greater than 7/32” as manufactured.
D. Tire models must not appear on the following list, which may be
altered at any time by the SEB upon notification of the membership.
Pirelli P Zero Corsa
14.4 WHEELS
Any wheels are allowed with widths up to the following:
STF, STC, STS, STR (AWD) – 7.5”
STX (AWD) – 8.0”
STX (2WD), STR (2WD) – 9.0”
STU – unlimited
A. Shock absorber bump stops may be altered or removed.
B. Any shock absorbers may be used. Shock absorber mounting brackets which serve no other purpose may be altered, added, or replaced,
provided that the attachment points on the body/ frame/subframe/
chassis/suspension member are not altered. This installation may
incorporate an alternate upper spring perch/seat and/or mounting
block (bearing mount). The system of attachment may be changed.
The number of shock absorbers shall be the same as Stock. No
shock absorber may be capable of adjustment while the car is in motion, unless fitted as original equipment. MacPherson strut equipped
cars may substitute struts, and/or may use any insert. This does not
allow unauthorized changes in suspension geometry or changes in
attachment points (e.g., affecting the position of the lower ball joint
or spindle). It is intended to allow the strut length changes needed to
accommodate permitted modifications which affect ride height and
suspension travel.
14.6 BRAKES
A. Non-standard brake rotors may be used provided they are of equal
or larger dimensions (diameter and thickness) and made of ferrous
material (e.g. iron). Thickness includes the individual plates of a
vented rotor, as well as the overall dimension. The diameter for replacement rotors is measured at the minimum outside dimension.
Aluminum rotor hats are allowed. Cars originally equipped with solid
(non-vented) rotors may utilize vented rotors. Cross-drilled and/or
slotted brake rotors may be fitted provided all such voids are within
the disc area, and comprise no more than 10% of that area. Brake
calipers and mounting brackets may be replaced provided they bolt
to the standard locations and the number of pistons is equal to or
greater than standard. A functioning emergency brake of the same
type, operation, and actuation as OE must be present. Drum brakes
may be replaced with disc brakes of a diameter equal to or greater
than the inside diameter of the standard drum. Such conversions
must be bolted, not welded, to the axle/trailing arm/upright, and must
include an integral, redundant emergency brake. Changes to backing plates/dust shields/brake lines to accommodate these changes
are permitted but may serve no other purpose.
B. Brake lines may be substituted with alternate DOT approved flexible
brake lines.
C. Air ducts may be fitted to the brakes, provided that they extend in a
forward direction only, and that no changes are made in the body/
structure for their use. They may serve no other purpose.
D. Original equipment ABS braking systems may be electrically disabled, but may not be removed or altered in any other way.
Substitution, addition, or removal of any anti-roll bar(s) is permitted.
Bushing material, method of attachment, and locating points are unrestricted. This does not authorize the cutting of holes to route the bar(s)
or links. Components such as anti-roll bars and strut housings that
serve dual purposes by also functioning as suspension locators may
not be modified in ways that change the suspension geometry or steering geometry. Non-standard lateral members which connect between
the brackets for the bar, including allowed strut bars per 14.2.G, are
permitted.
14.8 SUSPENSION
A. Ride height may only be altered by suspension adjustments, the
use of spacing blocks, leaf spring shackles, torsion bar levers, or
change or modification of springs or coil spring perches. This does
not allow the use of spacers that alter suspension geometry, such as
those between the hub carrier and lower suspension arm. Springs
must be of the same type as the original (coil, leaf, torsion bar, etc.)
and except as noted herein, must use the original spring attachment
points. This permits multiple springs, as long as they use the original
mount locations. Coil spring perches originally attached to struts or
shock absorber bodies may be changed or altered, and their position
may be adjustable. Spacers are allowed above or below the spring.
Suspension bump stops may be altered or removed.
B. Suspension bushings may be replaced with bushings of any materials (except metal) as long as they fit in the original location. Offset bushings may be used. In a replacement bushing the amount
of metal relative to the amount of nonmetallic material may not be
increased. This does not authorize a change in type of bushing (for
example ball and socket replacing a cylindrical bushing), or use of
a bushing with an angled hole whose direction differs from that of
the original bushing. If the Stock bushing accommodated multi-axis
motion via compliance of the component material(s), the replacement bushing may not be changed to accommodate such motion
via a change in bushing type, for example to a spherical bearing or
similar component involving internal moving parts. Pins or keys may
be used to prevent the rotation of alternate bushings, but may serve
no other purpose than that of retaining the bushing in the desired
position.
C. The following allowances apply to strut-type suspensions: Adjustable
camber plates may be installed at the top of the strut and the original
upper mounting holes may be slotted. The drilling of holes in order to
perform the installation is permitted. The center clearance hole may
not be modified. Any type of bearing or bushing may be used in the
adjustable camber plate attachment to the strut. The installation may
block (bearing mount). Any ride height change resulting from installation of camber plates is allowed. Caster changes resulting from the
use of camber plates are permitted.
D. Differential mount bushings may be replaced, but must attach in the
factory location(s) without additional modification or changes. Differential position may not be changed. The amount of metal in a
replacement bushing may not be increased relative to the amount of
metal found in a standard bushing for the particular application. Solid
metal bushings are specifically prohibited.
E. Transmission mounts may be replaced, but must attach in the factory
location(s) without additional modification or changes. Transmission
position may not be changed. The amount of metal in a replacement
mount may not be increased relative to the amount of metal found in
a standard mount for the particular application. Solid metal mounts
are specifically prohibited.
F. Steering rack bushings may be replaced, but must attach in the factory location(s) without additional modification or changes. Steering
rack position may not be changed. The amount of metal in a replace14. Street Touring® Category — 85
ment bushing may not be increased relative to the amount of metal
found in a standard bushing for the particular application. Solid metal
bushings are specifically prohibited. This does NOT allow shimming
or otherwise relocating the steering rack.
G. Camber bolts may be installed providing these parts use the original,
unmodified mounting points and meet the restrictions specified in
14.5.B. Caster changes resulting from the use of camber bolts are
permitted.
H. Solid axle suspension allowances:
1. Addition or replacement of suspension stabilizers (linkage connecting the axle housing or DeDion to the chassis, which controls
lateral suspension location) is permitted.
2. Traction bars or torque arms may be added or replaced.
3. A Panhard rod may be added or replaced.
4. The upper arm(s) may be removed, replaced, or modified, and the
upper pickup points on the rear axle housing may be relocated.
5. The lower arms may not be altered, except as permitted under
14.8.B, or relocated. Methods of attachment and attachment
points are unrestricted, but may serve no other purpose (e.g.
chassis stiffening). This does not authorize removal of a weldedon part of a subframe to accommodate the installation.
I. Camber kits, also known as camber compensators, may be installed.
These kits consist of either adjustable length arms or arm mounts
(including ball joints) that provide a lateral adjustment to the effective
length of a control arm. Alignment outside the factory specifications
is allowed. The following restrictions apply:
1. On double/unequal arm (e.g. wishbone, multi-link) suspensions,
only the upper arms OR lower arms may be modified or replaced,
but not both. Non-integral longitudinal arms that primarily control
fore/aft wheel movement (e.g. trailing arm(s) or link(s) of a multilink suspension) may not be replaced, changed, or modified.
2. On arm-and-strut (MacPherson/Chapman) suspensions, the lower
arms may be modified/replaced OR other methods of camber adjustment as allowed by paragraphs 14.8.B, C, or G may be used,
but not both.
3. On swing or trailing arm suspensions, the main arms may not be
modified or replaced, but lateral locating links/arms may be modified or replaced.
4. The replacement arms or mounts must attach to the original standard mounting points. All bushings must meet the requirements of
14.8.B. Intermediate mounting points (e.g. shock/spring mounts)
may not be moved or relocated on the arm, except as incidental
to the camber adjustment. The knuckle/bearing housing/spindle
assembly cannot be modified or replaced.
5. Changes in suspension geometry are not allowed except as incidental to the effective arm length change.
Note: Many modern suspension designs known by other names, actually function as double A-arm designs. These include the rear suspensions on 1988+ Honda Civic/Integra, Chrysler/Plymouth/Dodge
Neon, BMW E36, and most “multi-link” and are covered by section
14.8.I.1.
J. On strut-equipped cars, the strut’s lower integral mounting bracket,
for attachment to the upright or spindle, is unrestricted provided it attaches to the standard location. Any resulting change to the position
of the strut centerline is allowed. Such brackets shall serve no other
purpose. This does not allow for changes to the integral steering arm
on cars that have the steering arm integrated with the strut body.
K. Changes in alignment parameters that result directly from the use of
the allowed components are permitted. For example, the dimensional changes resulting from the use of a cylindrical offset bushing that
meets the restrictions of 14.8.B are allowed, including those resulting
from a change in the pivoting action to:
(1) about the mounting bolt, or
(2) about the bushing itself.
L. Subframe mount bushings may be replaced, but must attach in the
factory location(s) without additional modification or changes. Subframe position may not be changed. The amount of metal in a replacement bushing may not be increased relative to the amount of
A. The make, model number, and size of the battery may be changed
but not its voltage. Relocation of the battery or batteries is permitted
but not into the passenger compartment. If the battery is relocated
and the original battery tray can be removed by simply unbolting it,
the tray may be removed, or relocated with the battery. Holes may
be drilled for mounting or passage of cables. Longer cables may be
substituted to permit relocation. The number of battery or batteries
may not be changed from stock. The area behind the rearmost seat
is not considered to be within the passenger compartment. The area
under the rearmost seat is considered to be within the passenger
compartment. Battery allowances do not apply to electric and hybridelectric vehicles.
B. The addition of electrical grounding cables and associated distribution blocks/terminals is permitted. Holes may be drilled for mounting
only. This does not permit the use of electrical enhancement components such as condensers, voltage controllers, etc.
14.10 ENGINE AND DRIVETRAIN
A. Internal baffling of oil pans may be added or modified. Addition or
modification of windage trays, crankshaft scrapers, and oil pump
pickups is not allowed.
B. Original equipment traction control systems may be electrically disabled, but not removed or altered in any other way.
C. The air intake system up to, but not including, the engine inlet may be
modified or replaced. The engine inlet is the throttle body, carburetor, compressor inlet, or intake manifold, whichever comes first. The
existing structure of the car may not be modified for the passage of
ducting from the air cleaner to the engine inlet. Holes may be drilled
for mounting. Emissions or engine management components in the
air intake system, such as a PCV valve, or mass airflow sensor, may
not be removed, modified, or replaced, and must retain their original
function along the flow path.
D. Exhaust manifolds and headers (including downpipes) may be replaced with alternate units. Mounting brackets/hardware which serve
no other purpose are considered part of the exhaust components.
E. Catalytic Converters - Any high flow catalytic converter(s) are allowed, but must attach within six inches of the original unit. Multiple
catalytic converters may be replaced by a single unit. The inlet of the
single replacement converter may be located no further downstream
than 6” along the piping flow path from the original exit of the final
OE converter.
F. The engine management system parameters and operation may be
modified only via the methods listed below. These allowances also
apply to forced induction cars, except that no changes to standard
boost levels, intercoolers, or boost controls are permitted. Boost
changes indirectly resulting from allowed modifications are permissible, but directly altering or modifying the boost or turbo controls,
either mechanically or electronically, is strictly prohibited. Traction
control parameters may not be altered. Any standard OBD communications port functionality must remain. The Check Engine Light
(CEL) or Malfunction Indicator Light (MIL) may be disabled via software. Alternate software maps which violate these restrictions may
not be present during competition, regardless of activation.
1. Reprogrammed ECU (via hardware and/or software) may be used
in the standard housing.
2. Supplementary (“Piggyback”) ECU may be used subject to the
following restrictions:
a. Connects between the standard ECU/PCM and its wiring harness only.
b. Must be plug-compatible with the standard ECU/PCM (no splices).
3. Electronic components may be installed in-line between an engine’s sensors and ECU. These components may alter the signal
coming from the sensor in order to affect the ECU’s operation of
engine management system. Example: fuel controllers that modify the signal coming from an airflow sensor.
4. Fuel pressure regulators may be replaced in lieu of electronic alterations to the fuel system. It is not permitted to electronically
modify the fuel system AND replace a fuel pressure regulator.
5. Ignition timing may be set at any point on factory adjustable distributor ignition systems.
6. VTEC controllers and other devices may be used which alter the
timing of factory standard electronic variable valve timing systems.
G. Any mechanical shift linkage may be used.
H. Any accessory pulleys and belts of the same type (e.g., V-belt, serpentine) as standard may be used. This allowance applies to accessory pulleys only (e.g., alternator, water pump, power steering
pump, and crankshaft drive pulleys). It does not allow replacement,
modification, or substitution of pulleys, cogs, gears, or belts which
are part of cam, layshaft, or ignition drive or timing systems, etc.
Any crankshaft damper or pulley may be used. SFI-rated dampers
are recommended. Supercharged cars may not change the effective
diameter of any pulley which drives the supercharger.
I. Upper engine shields made of plastic material, the purpose of which
is to hide mechanical components in the engine compartment, may
be removed if they have a solely aesthetic and/or acoustic function.
J. Engine mounts may be replaced, but must attach in the factory
location(s) without additional modification or changes. Engine position may not be changed. The volume of metal in a replacement
mount may not be increased relative to the volume of metal found
in a stock mount for the particular application. Solid metal mounts
are specifically prohibited. Any non-metallic inserts may be used.
All components between the engine and the mounting structure are
considered to be part of the motor mount assembly and therefore
comprise the motor mount.
Hydraulic shock type rear engine locators, or bobble struts may be
replaced by manufacturer’s performance part, or aftermarket replacement part. This part must retain factory dimensions and attachment points, including factory design. (Example: If factory locator/
bobble strut is gas or hydraulic piston type, replacement part must
be gas or hydraulic piston type. No solid mounts may be substituted.)
K. Limited Slip Differentials
STC, STS, STF – No limited slip differentials are permitted except for
factory standard viscous coupler type units.
STX, STU, STR – Only standard (as defined in Section 12.4) limited
slip differentials (LSD) are allowed on AWD vehicles. For AWD
vehicles that did not come with any type of limited slip differential
(including center differential or transfer case), a single aftermarket
LSD may be added. 2WD vehicles may use any LSD unit.
14.11 OUT OF PRODUCTION CARS
Where a car is out of production and the manufacturer is either out of
business, stocks no parts or no longer has a required part, a part of any
origin but as similar as possible to the original may be substituted. The
entrant must be prepared to show documentary evidence that one of
the three circumstances above applies and that the substituted part is
as similar as possible under the circumstances. Substitute parts which
provide improvements in performance (e.g. superior gearing, lighter
weight, better camshaft profile, etc.) are not permitted under this allowance.
15. STREET PREPARED CATEGORY
Cars running in Street Prepared Category must have been series produced with normal road touring equipment, capable of being licensed
for normal road use in the United States, and normally sold and delivered through the manufacturer’s retail sales outlets in the United
States. Cars not specifically listed in Stock or Street Prepared Category
classes in Appendix A must have been produced in quantities of at least
1000 in a 12 month period to be eligible for Street Prepared Category.
A vehicle may compete in Street Prepared Category if the preparation
of the vehicle has not exceeded the allowable modifications of Stock
Category, except as specified below. However, the distinction between
different years/models used in Stock Category does not apply in Street
Prepared Category. Example: Porsche 911 models that are listed on
the same line are considered the same.
Cars listed as eligible in and prepared to the current national Improved
Touring rules are permitted to compete in their respective Street Prepared classes. Neither Street Prepared nor Improved Touring cars are
permitted to interchange preparation rules. Improved Touring cars may
use tires which are eligible under current IT rules even if they are not
eligible in Street Prepared.
Cars listed as eligible in and prepared to the current American Sedan
road race rules are permitted to compete in Class B Street Prepared.
Neither Street Prepared nor American Sedan cars are permitted to interchange preparation rules. American Sedan cars may use tires which
are eligible under current AS rules even if they are not eligible in Street
Prepared.
Cars listed as eligible in and prepared to the current national Touring
category rules are permitted to compete in their respective Street Prepared classes. Neither Street Prepared nor Touring cars are permitted
to interchange preparation rules. Touring cars may use tires which are
eligible under current Touring rules even if they are not eligible in Street
Prepared.
Cars listed as eligible in and prepared to the current national Street
Touring (ST) class rules are permitted to compete in their respective
Street Prepared classes, with the additional allowance that they may
use any tire which meets the requirements of 15.3 and fits on the STlegal wheels and within the ST-legal bodywork.
Cars eligible for the current Spec Miata rules are permitted to compete
in class D Street Prepared, with the additional allowance that they may
use any size of any tire which meets the requirements of 15.3 and fits
on the Spec Miata allowed wheels and within the allowed bodywork.
Spec Miata cars in DSP may not intermix use of the Spec Miata and
Street Prepared allowances. The competitor is responsible for being
in possession of the Spec Miata rules and for proving that his/her car
conforms to the rules.
15. Street Prepared Category — 91
Cars listed as eligible in and prepared to the current National B-Spec/
SSCRegulations are permitted to compete in their respective Street
Prepared Classes. Neither Street Prepared not B-Spec SSC cars are
permitted to interchange preparation rules. B-Spec.SSC cars may use
tires which are eligible under current Club Racing Showroom Stock
rules even if they are no eligible in Street Prepared.
While the rules of the Street Prepared Category have remained essentially the same, the laws governing various aspects of street-driven
vehicles have changed over time. The original concept of this category
as made up predominantly of street-driven vehicles has been rendered
inappropriate. The SCCA does not encourage or condone the breaking
of laws governing pollution control systems or the alteration of streetdriven vehicles contrary to state and federal laws regarding their use. It
continues to be the responsibility of the individual to comply with such
state and federal laws.
Specific vehicle classifications are located in Appendix A of these rules.
A. All Allowable modifications permitted in Stock Category are allowed.
B. Street Prepared vehicles may only be modified in excess of Stock
Category rules in the following ways. Any modification not specifically
authorized by the Stock Category or Street Prepared rules is prohibited. No unauthorized modifications are permitted in order to accommodate authorized modifications (e.g., non-stock hood scoops or
holes necessary for carburetor clearance). Structural modifications,
such as the addition of members known as “jacking rails”, are not
permitted unless specifically authorized herein.
C. Equipment and/or specifications may be exchanged between different years and models of a vehicle if:
(a) the item is standard on the year/model from which it was taken,
and
(b) the years/models are listed on the same line of Appendix A (Street
Prepared Classes).
The updated/backdated part or the part to which it is to be attached
may not be altered, modified, machined, welded, or otherwise
changed to facilitate the updating/backdating allowance. Standard
factory installation methods, locations, and configurations are allowed. The updating and/or backdating of engines, transmissions,
transaxles, and/or unibodies must be done as a unit; component
parts and specifications of these units may not be interchanged.
Cars not listed in the Street Prepared sections of Appendix A may
not be updated/backdated until approved by the SEB and published
in the official SCCA publication.
D. Alternate computer control modules may be used whenever an
equivalent change to the conventional system is allowed. For ex92 — 2012 SCCA® National Solo® Rules
ample, alternate computer module control of ignition settings or fuel
injection is allowed.
E. Air conditioning systems may be removed in whole or in part. This
rule should not be interpreted to allow modification of the heater system.
F. On all forms of suspension, camber/caster adjustment within factory specifications may be achieved by the use of shims or eccentric
bushings. The intent of this allowance is to permit cars to be restored
to within factory-allowed specification ranges, not to provide an additional method beyond those permitted in Section 15.8 to obtain
alignment settings beyond the factory specifications.
15.2 BODYWORK
Vehicles may only exceed the allowances of 13.2 as specified herein.
A. Fenders and bumpers may be modified for tire clearance. This includes the portion of a hood which serves as a fender/wheel well,
where applicable. This does not permit modifications to the chassis
or bodywork inboard of the vertical plane of the hub/wheel mounting
face (at rest, with front wheels straight ahead). Flares may be added
although tires may extend beyond the bodywork. Replacement of
complete hood, flared fenders, or quarter panels is prohibited. Plastic and rubber wheel well splash shields may be modified for tire
clearance and for installation of fender flares as allowed herein.
B. Factory rub strips, emblems, and mud flaps may be removed
C. Strut bars (per Section 12) are permitted with all types of suspensions, subject to the following constraints:
1. A two-point strut bar may be added, removed, modified, or substituted, but only with another two-point strut bar.
2. A triangulated (3-point) strut bar may be removed, modified, or
substituted; substitution may be with either a triangulated or a twopoint strut bar. The connection to the chassis (i.e., firewall, bulkhead, etc) must be in the standard location.
3. Lower suspension braces must be attached to the lower suspension pickup point locations on the chassis within two inches (2”,
50.8 mm) in any direction of the actual suspension attachment to
the chassis.
4. Except for standard parts, no connections to other componenets
are permitted.
Additional holes may be drilled for mounting bolts. Interior trim panels may be modified to allow installation of strut bars. Holes or slots
may be no larger than necessary and may serve no other purpose.
This does not permit any modifications to the frame or unibody beyond the allowed mounting holes.
D. Subframe mount bushings may be replaced, but must attach in the
factory location(s) without additional modification or changes. Subframe position may not be changed. The amount of metal in a replacement bushing may not be increased relative to the amount of
E. Longitudinal (fore-aft) subframe connectors (SFCs) are permitted
with the following restrictions:
1. They must only connect previously unconnected boxed frame rails
on unibody vehicles.
2. Each SFC must attach at no more than three points on the unibody (e.g. front, rear, and one point in between such as a seat
mount brace or rocker box brace).
3. SFCs must be bolted or welded, but welding must be to the OE
subframe stampings, not to the floor pan in between.
4. No cutting of OE subframes or floorpan stampings is permitted.
Drilling is permitted for mounting bolts only.
5. No cross-car/lateral/triangulated connections directly between the
driver’s side and passenger’s side SFCs are permitted. Connections to OE components such as tunnel braces or closure panels
via bolts are allowed and count as the third point of attachment.
No alteration to the OE components is permitted.
6. SFCs may not be used to attach other components (including but
not limited to torque arm front mounts or driveshaft loops) and
may serve no other purpose.
F. The driver and front passenger seats may be replaced, with the following restrictions: Seats must be securely mounted per 3.3.3.B.2.
The seating surface must be fully upholstered. Any replacement
seat must be a full back, bucket-type automobile seat incorporating
a functional headrest. Kart seats, low-back dune buggy seats, and
other similar types of seat are expressly prohibited. Cars may have
no fewer than the standard number of seats. The seat tracks are
considered part of the seat and may be substituted. Alternate seat
tracks may serve no other purpose. The standard seat belts may be
removed to facilitate the installation of alternate restraints complying with safety requirements. An alternate seat which replaces an
airbag-equipped seat is not required to have an airbag.
G. Any steering wheel may be used. An alternate wheel which replaces
an airbag-equipped wheel is not required to have an airbag. An alternate wheel is not required to have a horn button.
H. Airbags may be electrically disabled but not removed unless explicitly allowed.
I. Spoilers/splitters and cosmetic trim pieces are permitted. Side skirts
may not be used. Spoilers/splitters must comply with the following
subsections. The intent of this allowance is to accommodate com94 — 2012 SCCA® National Solo® Rules
monly available appearance kits, and replicas thereof, which have
no significant aerodynamic function at Solo speeds.
1. A spoiler/splitter may be added to the front of the car below the
bumper. It may not extend rearward beyond the front most part
of the front wheel well openings, and may not block normal grille
or other openings, or obstruct lights. Splitters may not protrude
beyond the bumper. Openings may not be used for the purpose
of ducting air to the radiator or oil cooler, but they may allow air
to flow through a permitted oil cooler provided no ducting is used.
The spoiler may not function as a wing.
2. A spoiler may be added to the rear of the car provided it complies
with either of the following:
a) It is a production rear spoiler which is standard or optional
equipment of a US model of the vehicle, or an exact replica in
an alternate material.
b) It is a non-production rear spoiler which is mounted to the rearmost portion of the rear hatch, deck, or trunk lid. The spoiler
may extend no more than 10 inches from the original bodywork in any direction. Alternatively, in a hatchback, the spoiler
may be mounted to the rear hatch lid at or near the top of the
hatch; in such a configuration the spoiler may extend no more
than 4 inches from the original bodywork in any direction. The
spoiler may be no wider than the original bodywork, and it shall
not protrude beyond the overall perimeter of the bodywork as
viewed from above. The use of endplates is prohibited. Angle of
attack is free. The spoiler may not function as a wing.
J. Rollover structures
1. Roll bars must comply with Section 13.2.H in Stock category.
2. Roll cages must comply with the following:
a. The roll cage need not be removable. It shall be bolted or welded to the car.
b. The cage shall attach to the car at no more than 8 points, consisting of the basic cage with 6 attachment points, and 2 additional optional braces.
c. The forward part of the cage shall be mounted to the floor of the
vehicle. If used, the 2 optional braces referred to in (2) shall be
mounted, one on either side, from the forward section of the
cage to the firewall or front fender wells. No braces shall pass
through the front firewall.
d. Roll cages that utilize NASCAR-style door bars that protrude
into the door cavity must comply with the GCR roll cage requirements for production-based cars.
e. Roll cages which utilize door bars that protrude into the door
panel must comply with all Club Racing GCR requirements for
roll cages.
Installation of roll cages in Street Prepared cars must follow the
same standards for interior modifications to accommodate the
cage installation as those which are applicable to Showroom
Stock or Touring cars in Club Racing.
K. The use of a fuel cell which complies with GCR requirements is permitted, provided all of the following additional restrictions are met:
1. The capacity of the cell may differ by no more than 20% from that
of the original tank.
2. The location of the cell may differ from that of the original tank by
no more than six inches in any direction.
3. The car meets all applicable Club Racing Time Trials safety standards, including those for rollover protection and the installation of
a fire extinguisher.
L. Fuel tank changes are permitted only as allowed under 15.1.C and
15.2.K. No additional tanks or reservoirs may be used.
M. Accelerator, brake, and clutch pedals may utilize substitute covers of
unrestricted origin, shape, and size, provided they meet the following requirements: covers must be securely attached, provide a nonslip surface, not interfere with each other’s operation, and must be
deemed safe at Tech Inspection. A clutch pedal stop may be added.
N. The OE radio may be removed. The OE sound system components,
except wiring, may be removed. Any visible holes which result from
the removal of such equipment must be covered.
O. Sunroof-equipped cars may be converted to a solid-roof configuration provided a model without a sunroof is listed on the same line in
Appendix A.
P. Fog lights may be removed.
Q. Interior rear view mirror and sun visors (and mounting hardware provided it serves no other purpose) may be removed or replaced.
15.3 TIRES
Tires must meet the eligibility requirements for Stock Category with the
following exception: the list of non-eligible tires in Section 13.3.A is replaced with the following list, which may be altered at any time by the
SEB upon notification of membership.
15.4 WHEELS
A. Wheels of any diameter, width, or offset may be used. Aftermarket
wheels may be modified to install OE tire pressure sensors.
B. Wheel spacers are permitted. Wheel studs and knock-off wheel drive
pegs may be changed in length and diameter. Wheel bolts may be
replaced with studs and nuts.
A. Shock absorber bump stops may be altered or removed.
B. On cars with lever-type shock absorbers, a tube-type shock absorber
may be added. If the lever-type shock serves no other purpose, it
must be removed. If the lever-type shock serves any other purpose,
it must be retained.
C. Any shock absorbers may be used. Shock absorber mounting brackets which serve no other purpose may be altered, added or replaced,
provided that the attachment points on the body/ frame/subframe/
chassis/suspension member are not altered. The installation may
block (bearing mount). The system of attachment may be changed.
The number of shock absorbers shall be the same as Stock. No
shock absorber may be capable of adjustment while the car is in motion, unless fitted as original equipment. MacPherson strut equipped
cars may substitute struts, and/or may use any insert. This does not
allow unauthorized changes in suspension geometry or changes in
attachment points (e.g., affecting the position of the lower ball joint
or spindle). It is intended to allow the strut length changes needed to
accommodate permitted modifications which affect ride height and
suspension travel. This allowance differs from Improved Touring Allowance 9.1.3.D.5.b.1.
D. On strut suspensions using a non-standard lower control arm (as defined by Section 15.8.H.2), an alternate upper spring perch/seat and/
or mounting block (bearing mount) as described in Section 15.5.C
may be used provided it offers no camber/caster adjustment beyond
standard.
15.6 BRAKES
A. Any brake line, master cylinder, vacuum brake booster, or brake proportioning valve that meets the requirements of 3.3.3.B.12 may be
used. This does not allow multiple separate cylinders. A single master cylinder brace may be added provided it is bolt-on and serves no
other purpose.
B. “Safety brakers” and units such as the “Brake Guard System” are
permitted.
C. ABS braking systems may be disabled, but not removed; brake
boosters may be removed, modified, substituted, or added.
D. Alternate brake rotors are permitted, subject to the following restrictions:
1. Rotors must be ferrous metal except for standard parts. Aluminum
rotor hats are allowed. Rotor dimensions (diameter and thickness)
must be equal to or greater than standard parts. Cars originally
equipped with solid (non-vented) rotors may utilize vented rotors.
2. Cross-drilled and/or slotted brake rotors may be used. Slots/holes
are permitted only in the braking area of the rotor. Rotors featuring
a drum-type parking brake in the hat area of the rotor may not be
drilled or slotted in the parking brake area.
E. Drum brakes may be replaced with disc brakes. Disc brake rotors
for such a conversion must be equal to or greater in diameter than
the inside diameter of the standard brake drum. Changes to backing
plates/mounting brackets/brake lines to accommodate this change
are permitted but may serve no other purpose. Drum-to-disc brake
conversions must be bolted, not welded to the axle/control arm/upright.
F. Air ducts may be fitted to the brakes, provided that no changes are
made in the body/structure for their use. They may serve no other
purpose. Backing plates and dirt shields may be modified or removed.
G. A functional, redundant emergency (parking) brake must be present.
H. Brake calipers may be replaced, provided the number of pistons
is equal to or greater than the original number of pistons. Caliper
mounting brackets may be replaced to accommodate this change,
but may serve no other purpose. Alternate caliper brackets must bolt
to the original caliper bracket mounting location(s).
Substitution, addition, or removal of any anti-roll bar(s) is permitted.
Bushing material, method of attachment, and locating points are unrestricted. This does not authorize removal of a welded-on part of a subframe to accommodate the installation, or the cutting of holes to route
the bar or links. Non-standard lateral members which connect between
the brackets for the bar, including allowed strut bars per 15.2.C, are
permitted.
The bar may serve no other purpose which is not explicitly permitted
elsewhere herein. Components such as anti-roll bars and strut housings which serve dual purposes by also functioning as suspension locators may not be modified or substituted in ways which change the
suspension geometry or steering geometry, and may not be installed in
positions (e.g. upside down) other than that of the original configuration.
15.8 SUSPENSION
A. Ride height may only be altered by suspension adjustments, the use
of spacing blocks, leaf spring shackles, torsion bar levers, or change
or modification of springs or coil spring perches. This does not allow
the use of spacers which alter suspension geometry, such as those
between the hub carrier and lower suspension arm. Springs must be
of the same type as the original (coil, leaf, torsion bar, etc.) and except as noted herein, must use the original spring attachment points.
This permits multiple springs, as long as they use the original mount
locations. Coil spring perches originally attached to struts or shock
absorber bodies may be changed or altered, and their position may
be adjustable. Spacers are allowed above or below the spring.
B. Suspension bump stops may be altered or removed.
C. Suspension bushings may be replaced with bushings of any materials (except metal) as long as they fit in the original location. Offset bushings may be used. In a replacement bushing the amount
of metal relative to the amount of non-metallic material may not be
increased. This does not authorize a change in type of bushing (for
example ball and socket replacing a cylindrical bushing), or use of
a bushing with an angled hole whose direction differs from that of
the original bushing. If the Stock bushing accommodated multi-axis
motion via compliance of the component material(s), the replacement bushing may not be changed to accommodate such motion
via change in bushing type, for example to a spherical bearing or
similar component involving internal moving parts. Pins or keys may
be used to prevent the rotation of alternate bushings, but may serve
no other purpose than that of retaining the bushing in the desired
position. Differential mount bushings are not considered to be suspension bushings and are not covered by this allowance.
D. Differential mount bushings may be replaced, but must attach in the
factory location(s) without additional modification or changes. Differential position may not be changed. The amount of metal in a
replacement bushing may not be increased relative to the amount of
E. Steering rack bushings may be replaced, but must attach in the factory location(s) without additional modification or changes. Steering
rack position may not be changed. The amount of metal in a replacement bushing may not be increased relative to the amount of metal
found in a standard bushing for the particular application. Solid metal
bushings are specifically prohibited. This does NOT allow shimming
or otherwise relocating the steering rack.
F. The following allowances apply to strut-type suspensions: Adjustable
camber plates may be installed at the top of the strut, and the original
upper mounting holes may be slotted. The drilling of holes in order
to perform the installation is permitted, but the center clearance hole
may not be modified. Any type of bearing or bushing may be used in
the adjustable camber plate attachment to the strut. The installation
may incorporate an alternate upper spring perch/seat and/or mounting block (bearing mount). Any ride height change resulting from installation of camber plates is allowed. Caster changes resulting from
the use of camber plates are permitted.
G. Camber bolts may be installed, providing these parts use the original, unmodified mounting points. Caster changes resulting from the
use of camber bolts are permitted.
H. Camber kits, also known as camber compensators, may be installed.
These kits consist of either adjustable length arms or arm mounts
that provide a lateral adjustment to the effective length of a control
arm. Alignment outside the factory specifications is allowed. Caster
changes resulting from the use of camber kits are permitted. The following restrictions apply:
1. On double/unequal arm (e.g. wishbone, multi-link) suspensions,
only the upper arms OR lower arms may be modified or replaced,
but not both. Non-integral longitudinal arms that primarily control
fore/aft wheel movement (e.g. trailing arm(s) or link(s) of a multilink suspension) may not be replaced, changed, or modified.
2. On arm-and-strut (MacPherson/Chapman) suspensions, the lower
arms may be modified/replaced OR other methods of camber adjustment as allowed by paragraphs 15.8.C, F, or G may be used,
but not both.
3. On swing or trailing arm suspensions, the main arms may not be
modified or replaced, but lateral locating links/arms may be modified or replaced.
4. The replacement arms or mounts must attach to the original standard mounting points. All bushings must meet the requirements of
15.8.C. Intermediate mounting points (e.g. shock/spring mounts)
may not be moved or relocated on the arm, except as incidental
to the camber adjustment. The knuckle/bearing housing/spindle
assembly cannot be modified or replaced. A non-standard ball
joint which is present in a compliant camber kit replacement control arm is permitted to offset from the standard point the spindle
mounting location from the control arm plane.
Note: Many modern suspension designs known by other names actually function as double A-arm designs. These include the rear suspensions on 88+ Honda Civic/Integra, Neon, E36 BMW, and most
‘multi-link’ and are covered by 15.8.H.1.
I. Solid axle suspension allowances:
1. Addition or replacement of suspension stabilizers (linkage connecting the axle housing or De Dion to the chassis, which controls
lateral suspension location) is permitted.
2. Traction bars or torque arms may be added or replaced.
3. A panhard rod may be added or replaced.
4. The upper arm(s) may be removed, replaced, or modified, and the
upper pickup points on the rear axle housing may be relocated.
5. The lower arms may not be altered, except as permitted under
15.8.C, or relocated.
Methods of attachment and attachment points are unrestricted, but
may serve no other purpose (e.g. chassis stiffening). This does not
authorize removal of a welded-on part of a subframe or bodywork to
accommodate the installation.
J. On strut-equipped cars, the strut’s lower integral mounting bracket,
for attachment to the upright or spindle, is unrestricted provided it
attaches to the stock location. Any resulting change to the position
of the strut centerline is allowed. Such brackets shall serve no other
purpose. This does not allow for changes to the integral steering arm
on cars that have the steering arm integrated with the strut body.
K. Changes in alignment parameters which result directly from the use
of allowed components are permitted. For example, the dimensional
changes resulting from the use of a cylindrical offset bushing which
meets the restrictions of 15.8.C are allowed, including those resulting from a change in the pivoting action to (a) about the mounting
bolt, or (b) about the bushing itself. Eccentric bolts are permitted for
suspension adjustment only if they are as specified by the factory,
per the last paragraph of 13.8.
Except for those with electric and hybrid powertrains, vehicles may only
exceed the allowances of 13.9 as specified herein.
A. Any ignition setting, adjustment, or system may be used, subject to
the requirements of 15.10.D. This does not prohibit the use of “twostep” rev limiters used when the car is stationary.
B. The make, model number, and size of the battery may be changed
but not its voltage.
C. Relocation of the battery or batteries is permitted but not into the
passenger compartment. If the battery is relocated and the original battery tray can be removed by simply unbolting it, the tray may
be removed, or relocated with the battery. Holes may be drilled for
mounting or passage of cables. Longer or shorter cables may be
substituted to permit relocation. The number of battery or batteries
may not be changed from stock. The area behind the rearmost seat
is not considered to be within the passenger compartment. The area
under the rearmost seat is considered to be within the passenger
compartment.
D. Any starter, generator, or alternator may be used in the original position. An alternator or generator must have an electrical output (including amperage) equal to or greater than the original equipment
unit. Any generator or alternator pulley and belt of the same type as
standard may be used (see 15.10.Y).
E. Wiring harnesses may not be removed in whole or in part. Wiring
connectors for emissions control devices are considered part of the
harness, not part of the emissions control system, and may not be
removed.
15.10 ENGINE AND DRIVE TRAIN
Except for those with electric and hybrid powertrains, vehicles may only
exceed the allowances of 13.10 as specified herein.
A. Engines must retain standard type lubricating system, but may have
any oil pan (Accusump-type systems allowed), oil pump and pickup,
oil coolers, oil or fuel filters. Fuel filters must be of automotive type
and may serve no other purpose; a substituted fuel filter may not be
used as a reservoir. Substituted fuel filters may not exceed one quart
total capacity. A permitted oil cooler may be positioned in an opening
in an allowed spoiler, provided no unauthorized modifications are
made in order to perform the installation. Any power steering fluid
cooler may be added.
B. Heat shields may be added.
C. Induction allowances are as follows:
1. Carburetors, fuel injection, and intake manifolds are unrestricted,
subject to 15.10.D. Alternate throttle linkage and connections to
facilitate installation of allowed induction systems are permitted,
but may serve no other purpose. If an induction system item is allowed to be removed and its original mounting bracket can be removed by simply unbolting it, the bracket may be removed as well.
2. Except for standard parts as defined in these rules, the external
use while on course of liquids, ice, dry ice, refrigeration systems,
vaporized compressed gases, etc. to reduce the temperature of
the intake air charge is prohibited. Wrapping of intakes with liquidsoaked fabric is not permitted.
3. As utilized only on engines originally equipped with forced induction, induction charge heat exchangers (known as “intercoolers” or
“charge air coolers (CACs)”) are unrestricted in size and configuration. Air-to-air CACs and radiators for air-to-liquid CACs must be
cooled only by the atmosphere, except for standard parts. Body
panels, fascias, or structural members may not be cut or altered
to facilitate CAC installation.
4. Turbochargers and/or superchargers (forced induction) may not
be added, changed, or modified (this does not allow ceramic coating of turbochargers). On vehicles originally equipped with forced
induction:
a) No hardware changes or alterations to turbocharger(s) or
supercharger(s), in size or number, are permitted. Turbochargers or superchargers may be updated/backdated only in conjunction with the accompanying complete engine unit.
b) No changes are allowed to waste gate(s) size, number, or location. No changes are allowed to variable-geometry turbine
(VGT) hardware.
c) No changes are allowed to supercharger drive system pulleys.
Belt tensioners may be added/changed to reduce belt slip.
d) No changes are permitted to blow-off/pop-off valves.
e) Compressor bypass valves (CBVs) are considered part of the
air intake system and may be added, replaced, or updated/
backdated independently of the other components of a forced
induction system.
f) Boost regulation systems, either electronic or mechanical, and
electronic fuel cuts referencing boost pressure may be altered
or modified except as prohibited herein. Boost pressure changes resulting from authorized changes are permitted.
D. Traction and/or stability control systems, as defined in 12.12, must
be standard parts at standard settings, or electronically disabled.
E. Air cleaner(s) may be changed or removed, velocity stacks may be
added.
F. Emission control devices may be modified or removed. This permits
the oil filler cap to be modified or substituted, but does not allow
valve covers or cam covers to be altered to install a breather or for
any other purpose.
G. Intake water injection systems are allowed.
H. Fuel lines and pumps are unrestricted except as specified herein,
as long as they do not pose a safety hazard. Fuel lines may be no
larger than 1/2” i.d. and may only connect to the original fuel tank or
allowed fuel cell. They may be no longer than necessary for reasonable and safe installation, and may serve no other purpose. A single
fuel feed line may be used. A single fuel return line may be used, and
a fitting for connecting it may be added at or near the top of the fuel
tank. This does not authorize “cool-cans”.
I. Exhaust manifolds and muffler systems are free, except that they
must be quiet and terminate behind the driver. Exhaust heat shields
may be removed. Rear- and mid-engine cars without exhaust headers/manifold systems may use any exhaust system that meets the
requirements of 3.5. This permits the removal of “heater boxes” in
order to install headers on such cars.
J. Engine mounts may be replaced, but must attach in the factory
location(s) without additional modification or changes. Engine position may not be changed. Hydraulic shock type rear engine locators,
or bobble struts, may be replaced by manufacturer’s performance
part or aftermarket replacement part. This part must retain factory
dimensions and attachment points, including factory design. (Example: If factory locator/bobble strut is gas or hydraulic piston type,
replacement part must be gas or hydraulic piston type.) If one or
more non-OE engine mounts are used, 15.10.K does not apply and
a torque suppression device may not be used.
K. One bolt-on torque suppression device may be used. A torque suppression device attaches from the engine to the body, frame, or sub15. Street Prepared Category — 103
frame in one location, and controls engine movement at that location
along a single axis only. It may serve no other purpose.
Examples of permitted devices:
1) a chain
2) a rod with spherical bearings at each end.
Examples of devices not permitted:
1) any link which confines movement along more than one axis.
2) an engine mounting plate, or one or more plates rigidly bolted
between the engine and the frame. Holes may be drilled to
mount a torque suppression device. The installation may not
include the welding of any plate(s) to the bodywork or to the
motor mount(s), nor may it include multiple non-parallel links.
If a torque suppression device is used, 15.10.J does not apply and
replacement engine mounts may not be used.
L. Engine cooling radiators may be replaced with alternate parts subject
to the following restrictions:
1. Radiator core dimensions (width, height, thickness) must be no
smaller than the standard part.
2. Radiator must mount to OE radiator mounts.
3. Fluid capacity and dry weight of the radiator must be no less than
that of the standard part. Installation of an alternate radiator may
serve no other purpose (e.g. to allow a cold air intake passage).
M. The engine fan and fan shroud (unless it serves another purpose,
e.g., as an alternator/generator mount) may be removed, modified
or replaced. Electrically driven fans are allowed. Flex fans are not
allowed.
N. Transmission mounts may be replaced, but must attach in the factory
location(s) without additional modification or changes. Transmission
position may not be changed. The amount of metal in a replacement
mount may not be increased relative to the amount of metal found in
a standard mount for the particular application. Solid metal mounts
are specifically prohibited.
O. On two-cycle engines, the ports must be of standard heights, size
and configuration; crankcase volume and reed plates must not be
altered.
P. Any metal clutch assembly, metal flywheel, or metal torque converter
that uses the standard attachment to the crankshaft may be used.
Non-metallic friction surfaces (e.g., clutch disks) are permitted. Dowel pins may be added. Any hydraulic clutch line may be used. Replacement or substitution of the clutch slave cylinder is permitted, but
this does not allow non-original methods of clutch actuation (e.g. pull
type versus push type).
Q. Any mechanical shift linkage may be used.
R. Limited slip differentials are permitted. This permits locked differentials, either by design, welding, or mechanical means. Differential
cases, internal differential parts, and axle stubs may be machined as
required for clearance and installation to the extent that material may
only be removed, not added, and the exterior of the case may not be
altered in any way. This machining may serve no other purpose. Any
other modifications or substitutions to accommodate the installation
of the limited slip differential must meet the requirements of 15.1.B
and 15.1.C.
S. Cylinders may be rebored to no more than 0.0472 in. over standard
bore and the appropriate standard oversize piston may be substituted. This overbore dimension is an absolute limit; no additional tolerance is permitted to accommodate wear. Cast or forged, non-stock
pistons of the same dimensions and configuration as original equipment pistons may be used. Additionally the replacement pistons must
be of the same weight or greater as the original equipment pistons.
Replacement pistons must match OE piston configuration exactly including quench area. The allowance for the use of aftermarket forgings vs. OE castings does not permit alternate piston dome designs.
This allowance does not permit alternative ring configurations.
T. Rotating and reciprocating parts may be balanced but not lightened.
U. Intake and exhaust ports and manifold openings may be matched
provided no change is made more than one inch from the port/manifold interface. Material may be removed to facilitate port matching,
but no material may be added.
V. Any transmission oil cooler may be used.
W. The engine cylinder head(s) may be milled only to that amount specified in the manufacturer’s workshop manual. If no amount is specified then a maximum of 0.010 in. may be milled.
X. Axle/halfshaft and driveshaft retention/location devices may be installed for safety reasons to control the motion of attached shafts
upon the failure of a coupling or universal joint. They may serve no
other purpose. This allowance does not include “C-clip eliminators.”
Y. Any crankshaft damper or pulley may be used. SFI-rated dampers
are recommended. Supercharged cars may not change the effective
diameter of any pulley which drives the supercharger.
Z. Any accessory pulleys and belts of the same type (e.g. V-belt, serpentine) as standard may be used. This allowance applies to accessory pulleys only (e.g., alternator, water pump, power steering
pump, and crankshaft drive pulleys). Supercharged cars may not
alter crankshaft/supercharger drive ratio. Alternate pulley materials
may be used. Idler pulleys may be used for belt routing in place of
items which the rules specifically allow to be removed, such as smog
pumps and air conditioning compressors. They may serve no other
purpose.
AA. Camshafts and related parts must remain standard except that alternate cam drive pulleys or gears may be used to adjust cam timing
if no variable cam and/or valve timing system exists as standard.
Type of cam drive (chain, belt, gear) must remain as standard. Alternate parts of the same general type (e.g. roller chain in place of “silent” chain) may be substituted. Mating parts (block, heads, covers,
retainers, etc.) may not be altered. Vehicles equipped with a variable cam and/or valve timing system as standard may use alternate
computer calibration to adjust cam and/or valve timing but may not
change or substitute cam drive components (hardware).
BB. Upper engine shields made of plastic material, the purpose of which
is to hide mechanical components in the engine compartment, may
be removed if they have a solely aesthetic and/or acoustic function.
15.11 OUT-OF-PRODUCTION CARS
Where a car is out of production and the manufacturer is either out of
business, stocks no parts or no longer has a required part, a part of any
origin but as similar as possible to the original may be substituted. The
entrant must be prepared to show documentary evidence that one of
the three circumstances above applies and that the substituted part is
as similar as possible under the circumstances. Substitute parts which
provide improvements in performance (e.g. superior gearing, lighter
weight, better camshaft profile, etc.) are not permitted under this allowance.
16. STREET MODIFIED CATEGORY
16.0.A. PURPOSE

3. STREET MODIFIED FWD (SMF) – Supplemental Class
All front-wheel-drive vehicles
16.1 ALLOWED MODIFICATIONS
A. All Stock, Street Touring, and Street Prepared category modifications
are authorized. Except as noted by these rules and the referenced
rules, vehicles must be as originally delivered including all road-going components such as lights, wipers, interior, heater, etc.
B. Competitors may pick and choose between all Stock, Street Touring,
Street Prepared, and Street Modified category allowances when preparing an SM car. Apparent conflicts between inherited rule sets from
16.1.A shall not prohibit any specific inherited allowance. Allowances
inherited from 16.1.A may not incorporate SM-specific allowances.
Foreign spec parts may not be used to substitute for parts which are
required to remain stock.
C. Brakes, including calipers, caliper mounts, disks, drums, lines, backing plates, pedals, boosters, master cylinders, handles, ABS systems, proportioning valves, etc. are unrestricted. Brake rotor/drum
friction surfaces must be 100% ferrous metallic. Carbon or ceramic
composite brake components (except pads) are expressly prohibited. Standard parts, per 12.4, are exempt from this restriction. A
functional, redundant emergency (parking) brake must be present.
D. Drivetrain and related components (induction, ignition, fuel systems,
etc.) are unrestricted except for the following limitations:
1. Engine block must be a production unit manufactured and badged
the same as the original standard or optional engine for that model. Badges that exist as marketing aliases for the manufacturer
will be recognized as equivalents. Swaps involving makes related
only at a corporate level are not recognized as equivalents. Models produced as a joint venture between manufacturers may utilize
any engine from any partner in the joint venture, provided that an
engine from the desired manufacturer was a factory option in that
particular model (e.g. Eagle Talon available originally with either a
Mitsubishi or Chrysler engine, may use any motor from Chrysler
or Mitsubishi). This allows engine blocks manufactured as production units for sale in other countries such as Japan or Germany.
2. Maximum engine displacements per class are specified in Appendix A.
3. Fuel System
a. Any fuel line(s) may be used. All non-standard fuel line(s) passing through the passenger compartment shall be made of met108 — 2012 SCCA® National Solo® Rules
al, metal braided hose, or equivalent (e.g., Nomex, Kevlar, or
nylon braided hose) with AN Series threaded couplings; or entirely covered and protected with a metal cover.
b. Any fuel pump(s), filter(s) and pressure regulator(s) may be
used. Such components may not be located in the passenger
compartment, but their location within the bodywork of the car
is otherwise unrestricted. If a mechanical pump is replaced,
a blanking plate may be used to cover the original mounting
point.
c. A cool-can, not exceeding one gallon in volume, may be used.
The cool-can may not be installed in the passenger compartment.
d. The fuel tank may be modified or replaced. If the fuel tank is
modified or replaced, the following restrictions apply:
1. No part of the fuel tank or fuel cell shall be closer than 6 inches to the ground unless enclosed within the bodywork and
mounted above the floor pan. A metal bulkhead is required
that provides total separation between the driver compartment and the compartment containing the fuel tank and/or
filler/neck. This includes fuel tanks that are flush mounted
with driver compartment panels or otherwise exposed to the
driver compartment. Fuel filler doors in the driver compartment must be positively fastened (non-metallic fasteners are
not allowed).
For the purposes of these rules, a fuel tank consisting of a
structure containing a fuel bladder is considered to be the
entire fuel cell, including the containing structure. The containing structure of a fuel cell does not qualify as a bulkhead.
A separate metal bulkhead must isolate the fuel cell from the
passenger compartment.
2. Internal body panels may be modified to accommodate the
installation of the fuel tank as long as such modifications
serve no other purpose. In the event installation includes encroachment into the driver’s compartment, a metal bulkhead
shall prevent exposure of the driver to the fuel tank.
3. Fuel tank breathers shall not vent into the driver/passenger
compartment.
4. Minimum capacity of a non-standard fuel tank/cell shall be
no less than five (5) gallons.
Motor and drivetrain mounts are considered part of these allowances, and any material is permitted. The allowances of 16.1.P
may be used to affix brackets, but these brackets shall serve no
purpose other than engine and drivetrain mounting (e.g. they
may not provide chassis stiffening).
E. Suspension components are unrestricted as long as they use the
original attachment points. For the purposes of this rule, “suspension” is defined as any item that is designed to move when a wheel
is deflected vertically. This includes shocks and struts, control arms,
steering knuckles, uprights, etc., but not tie rods, steering racks, and
subframes. In addition, shock absorber/strut upper mounts are to be
considered suspension components.
F. Steering modifications are permitted as follows:
1. Steering components, including the steering rack and/or box, tie
rods, idler arms, power assist devices, and related components,
may be replaced, added, moved, or removed. The steering column, within the passenger compartment, is specifically excluded
from this allowance. This does not permit removal or modification of column-mounted accessories. Wheel-mounted electrical
switches such as those for the horn, radio, cruise control, or shifter
may be relocated and/or replaced, or eliminated.
2. Rear-steer devices may be replaced with solid links.
3. Supplemental steering gear boxes, a.k.a. steering quickeners, are
allowed as long as they are mounted in accordance with 16.1.F.1.
4. Steering wheels and associated mounting hardware may be replaced. This does not permit removal or modification of the steering column or column-mounted accessories. OE wheel-mounted
electrical switches such as those for the horn, radio, cruise control, or shifter may be relocated and/or replaced, or eliminated.
G. Subframe connectors are allowed as per Street Prepared (15.2.E).
H. Subframe bushings may be replaced with bushings of any material
as long as they fit the original location. Offset bushings may not be
used.
I. Front hoods (engine covers), engine covers, trunk lids and hatches
not containing glass, front fenders, rear fenders not part of chassis structure (unibody), front & rear facias, and side skirts may be
modified or replaced, and may be attached with removable fasteners. Associated hardware including latches, hinges, window washer
nozzles, and hood liners may be modified, removed, or replaced.
This does not permit removal of the remainder of the window washer
system. Fenders may be flared as per Street Prepared. Non-metallic
fender liners may be modified, replaced, or removed.
J. Tires legal in Stock, Street Touring, or Street Prepared are permitted.
K. Rear passenger seat(s), including restraints and associated hardware may be removed.
L. Aerodynamic Aids: Wings may be added, removed, or modified. NonOE wings may only be attached to the rear deck/hatch area behind
the centerline of the rear axle. The total combined surface area of all
wings shall not exceed 8 square feet as calculated per Section 12.9.
The number of wing elements is limited to 2.
Wings, and any component thereof, may not extend beyond the vehicle width, as defined by the outermost portion of the vehicle doors,
less mirrors, door handles, rub strips, and trim. In addition, no portion
of the wing or its components may be more than 6” forward of the
rear axle, more than 0” beyond the rear most portion of the bodywork, or more than 6” above the roofline of the vehicle, regardless of
body style. For convertibles and roadsters, the highest portion of the
windshield frame will be considered the highest portion of the roof.
Reinforcements to the wing mounting area may be used, but may
serve no other purpose. Body panels to which a wing mounts must
remain functional (e.g. trunk lids and rear hatches must open). Wing
endplate surface area is limited to 200 square inches each and limited to a maximum of two.
Except for standard parts, wings designed to be adjustable while the
car is in motion must be locked in a single position.
Canards are allowed and may extend a maximum of 6 inches forward of front bodywork/fascia as viewed from above. No portion of
the canard may extend past the widest part of the front bodywork/
fascia as viewed from above. Canard area will be measured in the
same manner as wings using 12.10. Canard area may not exceed
15% of total wing allowance. The sum of canard area and rear wing
area may not exceed the total wing allowance.
M. Front splitters are allowed and shall be installed parallel to the
ground (within +/-3 degrees fore to aft) and may extend a maximum
of 6 inches from the front bodywork/fascia as viewed from above.
Splitters may not extend rearward past the centerline of the front
wheels. No portion of the splitter may extend beyond the widest part
of the front bumper/fascia as viewed from above.
N. T-Tops, targa tops, sunroofs, moonroofs, and similar roof-mounted
panels may be removed/replaced with alternate panels provided that
the area of interface is limited to the original perimeter of the t-top,
sunroof, etc. or utilizes the OE panel mount points, and that the contour of any replacement panel surface does not vary from the contour
of the part being replaced by more than 1 inch in any direction. The
material used to construct the alternate panel and the method used
to attach it to the interface is unrestricted. Any actuation mechanism
and the associated wiring, if any, may be removed.
O. Radio/Stereo and airbag equipment and/or its component parts, including wiring, control modules, antennas, amplifiers, speakers and
their enclosures, etc. may be removed provided the part added, removed, or replaced serves no other purpose. Any visible holes that
result from the removal of equipment must be covered with a cover of unrestricted material. Covers may be used to mount gauges,
switches, etc.
P. Any minor modification, intended to allow or facilitate any allowed
modification, is permitted as long as it does not provide any intrinsic
performance benefit in and of itself, does not provide a weight reduction of more than 1 lb, and is not explicitly prohibited elsewhere
within these rules.
This rule is intended to allow minor notching, bending, clearancing,
grinding; the drilling of holes; affixing, relocating, or strengthening of
brackets; removal of small parts, and similar operations performed
in order to facilitate the installation of allowed parts or modifications.
Minor strengthening, without relocation, of original chassis/suspension pickup points is allowed. Examples include welding washers
restricting control arm mounting bolt movement, local reinforcement
of control arm chassis mounts, etc.
Competitors are strongly cautioned to make the minimum amount of
modification required to affix a given part, and to not make unduly
tortured interpretations of this rule. Modifications to the firewall in
order to allow for increased engine setback, and any modification
that changes the location of a suspension pickup point, are explicitly
forbidden. Plastic under-trays and covers below the vehicle may be
removed or modified as necessary to facilitate other compliant modifications, but not added or enlarged.
Q. Ballast may be added. Ballast must be a maximum of 50 lbs. per
segment. It must be securely mounted within the bodywork.
R. OE side mirrors may be replaced by aftermarket units, provided they
mount in the same location, perform the same function as the OE
mirrors, and have a reflective surface area greater than 15 sq. in.
S. OE pop-up headlights may be replaced with static headlights, provided the replacement units are intended for automobile use on public roads as a primary means of illumination, and retain high and low
beams as originally provided by the manufacturer. Minor repositioning of the headlights is allowed to accommodate the alternate headlight, but the unit may not be relocated and the repositioning may
servce no other purpose. All associated hardware may be removed,
replaced or modified.
T. Alternate subframes are allowed to facilitate engine mounting only.
Suspension pick-up points on the subframe must retain standard geometry. Weight of the subframe must be equal or greater than the
standard unit.
16.2 MINIMUM WEIGHTS
Classes, displacements, and minimum weights are listed in Appendix
A. For the purpose of determining SM minimum weights, a mid-engine
vehicle is defined as one having a chassis configuration where the engine block is not located entirely in front of the driver’s seat, and is not
far enough back to be considered a rear-engine vehicle. Adjustments to
minimum weights are shown in Appendix A.
16.3 OTHER
Due to the inherent creative nature of this category of classes and the
resulting member questions about the intent and interpretation of the
rules, the SEB will issue clarifying Tech Bulletins on www.scca.com or
in the official SCCA publication on an as needed basis. Car constructors are cautioned against overly creative or tortured interpretations of
these rules. When in question, competitors should contact the SCCA
National Office for a clarification.

It is the intent of these rules to allow modifications useful and necessary in the preparation of a high performance, production based nonstreet-driven vehicle. The SCCA® will use the following guidelines
in the determination of suitability for classification in the Prepared
Category:
1. Cars classified shall retain their original design, structure, and
drive layout unless otherwise specified in these rules. If in doubt
about a modification, competitors should ask. If the rules do not
specifically authorize a modification, it is not permitted.
2. Cars running in Prepared Category must have been series produced with normal road touring equipment, capable of being licensed for normal road use in the United States, and normally
sold and delivered through the manufacturer’s retail sales outlets
in the United States. Cars not specifically listed in Prepared Category classes in Appendix A must have been produced in quantities
of at least 1000 in a 12-month period to be eligible for Prepared
Category.
3. The SCCA® may also class suitable non-production full-bodied
full-fendered strictly-specified cars into this category. Production
quantities, EPA approval, and DOT approval are not required. The
SCCA® may choose not to classify any such vehicle it deems
unsuitable for the Prepared category.
4. Within the scope of these rules, the terms “chassis” refers to the
minimal configuration of a car necessary to contain all of the running gear (drivetrain, suspension & steering) and to provide support for the body. For cars of “frameless” construction, the chassis
is the central contiguous assembly of stressed panels and subframes which form the basic structure necessary to contain all the
running gear of a car.
5. Specific allowances in Appendix A for a listed model supersede
the limitations of Section 17. Minimum weights shall be established making it possible for all cars to reach minimum weight with
reasonable modifications. The SEB recognizes that low minimum
weights ultimately result in higher costs to the competitor. The
rules shall discourage the use of high technology/high cost equipment. In some cases, this is accomplished by an outright ban on
the equipment. In other cases, this is accomplished through the
adjustments to minimum weight. See Section 17.11 for weight adjustments.
17.0.B. Specifications
The SCCA® shall publish specifications for each car specifically
classed in the Prepared Category section of Appendix A. These
specifications will at a minimum specify each vehicle’s allowed minimum weight and maximum wheel sizes.
17. Prepared Category — 115
1. Equipment and/or specifications may be exchanged between different years and models of a vehicle if:
a. the item is standard on the year/model from which it was taken,
and
b. the years/models are listed on the same line of Appendix A
(Prepared Classes). The updated/backdated part or the part
to which it is to be attached may not be altered, modified, machined or otherwise changed to facilitate the updating/backdating allowance unless the modification is specifically allowed by
these rules. Cars not listed in the Prepared Category sections
of Appendix A may not be updated/ backdated until approved
by the SEB and www.scca.com published in the official SCCA®
publication.
2. The SCCA® may recognize certain optional components. Some
non-original components may be made mandatory to obtain an
adjustment of competition potential. In all cases, these components shall be listed in Appendix A. No permitted or alternate
component or modification shall additionally perform a prohibited
function.
3. Requests for alteration, modification, and/or substitution of any
specification or component shall be submitted to the Club for approval. The approval process will include, but not be limited to, an
analysis of cost, availability, performance impact, rule enforceability, and competitor input.
The modifications defined in the Prepared Category Section are the
only allowed modifications. The rules in this section stand on their own;
they do not build upon the Stock or Street Prepared Category rules.
Modifications shall not be made unless specifically authorized herein.
No permitted component/modification shall additionally perform a prohibited function. If the rules do not specifically authorize a modification,
it is not permitted.
A. It is not permitted to make any changes, alterations, or modifications
to any component produced by the manufacturer, unless specifically
authorized by these rules.
B. Any minor modification, intended to allow or facilitate any allowed
modification, is permitted as long as it does not provide any intrinsic
performance benefit in and of itself, and is not explicitly prohibited
elsewhere within these rules. This rule is intended to allow minor
notching, bending, clearancing, grinding; the drilling of holes; affixing, relocating, or strengthening of brackets; removal of small parts,
and similar operations performed in order to facilitate the installation
of allowed parts or modifications. Competitors are strongly cautioned
to make the minimum amount of modification required to affix a given
part and to not make tortured interpretations of this rule. (e.g., mov116 — 2012 SCCA® National Solo® Rules
ing frame rails inboard, regardless of the reason, is considered to be
a tortured interpretation.)
17.2 BODYWORK AND STRUCTURE
The purpose of the following rules is to maintain recognizable external
features of the manufacturer’s make and model, while providing the
necessary safety and performance modifications. Restrictions regarding external body shape and belly pans are aimed at preventing attempts to obtain ground effects or streamlining.
A. The external shape of the body may only be changed where specifically authorized. Standard window openings, rain gutters, or
approved facsimiles shall be retained. All external trim and model
identification may be removed. Grilles may be removed, modified,
or substituted.
B. Chassis, frame, or subframe may be reinforced, provided components and attachments are not relocated except where specifically
permitted. Reinforcing does not authorize the use of belly pans forward of the firewall, or aft of the front edge of the rear wheel opening.
It is permitted to have jack points recessed into the rocker panels, or
to have one tube per side extending downward through the bottom of
the door, provided they do not extend beyond the overall width of the
car or in an unsafe or dangerous manner. No part of the bodywork or
chassis, to the rear of the front wheel opening, shall touch the ground
when both tires on the same side of the car are deflated.
C. The chassis, frame, or subframe may be notched or cut and brackets
may be added for the purpose of attaching alternate suspension or
drivetrain components, except that the firewall may not be modified
for engine block or cylinder head clearance. Holes may be cut to
provide clearance for authorized suspension and drivetrain components, through their entire range of travel. Additional structure may
be added in order to attach allowed components to the chassis.
D. Replacement of any chassis component (e.g., subframe) in its entirety by one of alternate construction, unless specifically permitted,
shall result in the vehicle being “in excess” of these rules and weight
penalties and/or competitive adjustments may apply.
E. The floor in the driver/passenger compartment may be modified for
installation of subframe connectors, exhaust components, and for
driveshaft clearance. When modified, the driver/passenger compartment must remain separate from any exhaust and driveshaft components. The modified area must be steel or aluminum and no more
than a four inch (4.0”; 101.6 mm) clearance is allowed between modified floor area and exhaust, or modified floor area and driveshaft
components.
Trunk floors may be modified, removed, or replaced. If replaced, the
trunk floor must be replaced with metal panels of similar shape to the
original. Removal of the trunk floor is allowable only when a metal
bulkhead separates the trunk area from the passenger compartment.
F. The firewall may be notched or recessed for clearance of exhaust
headers, electric lines, coolant lines, fuel-carrying lines, fuel pumps,
intercooling piping, carburetors, air horns, air cleaners, and distributor. Any material added to the firewall must be either steel or aluminum. This requires a sealed firewall between engine and passenger
compartment. This rule is for driver’s safety. Completely sealing all
firewall openings is strongly encouraged, but no gap may be larger
than 1/8 inch (0.125”; 3.2 mm), except around dynamic devices extending through the firewall (e.g., throttle linkage, transmission linkage or other mechanical devices) and should be sealed to the extent
that functioning of the device is not impaired. No more than 8 inches
(8”; 203.2 mm) clearance is allowed between modified firewall areas
and above listed components. The engine block, cylinder head, turbochargers, and/or superchargers may not intrude into the clearance
areas authorized herein.
G. Bumper components not integral to the bodywork may be modified,
substituted with a replica of alternate material, or removed provided
all projecting hardware is also removed. Bumper bracket holes in
the bodywork may be covered provided such covering serves no
other purpose. Bumper fascias integral with the bodywork may be
modified or substituted with a replica of alternate material. Internal
bumper components may be removed, replaced, or modified. Modified or replica bumpers/fascias must be of similar shape as standard
components, completely cover the area of the OE bumper/fascia,
and not confuse the identity of the vehicle.
H. All interior trim, dash boards, gauges, floor covering, carpet and upholstery panels and similar non-performance comfort or convenience
items may be removed or replaced.
I. The driver seat may be replaced with a seat of any origin. All passenger seats may be removed or replaced with seats of any origin.
Driver’s seat must remain on the standard side of the car and may
not cross the centerline of the car. The seat may be relocated fore/
aft by up to 12 inches (12.0”; 30.5 cm) based on the centerline of the
original front and rear mounting points. Rear bulkhead of the driver/
passenger compartment may not be removed to relocate seat and
driver’s seat may not extend rearward past the bulkhead.
J. Doors may be lightened and may be replaced by ones of alternate
materials. Doors may be pinned, but not bolted, to prevent their
opening in case of an accident. Quick release fasteners (e.g., Dzus
fasteners) are allowed. Standard door hinges and latch mechanisms
may be removed, but the doors shall be capable of being opened or
removed. Interior door panels may be removed or replaced and the
door window slots may be covered. Alternate attachment devices
may be added to hood and deck lid to supplement or replace the
latches. Hood and deck lid hinges may be removed.
K. Windows
1. All windows may be replaced with polycarbonate material. The front
windshield shall have a minimum thickness of ⅛ inch (0.125”; 3.16
mm). Tinting of the upper portion of the front windshield and the
entire portion of all other windows is allowed. All window replacements shall remain in the same position in the frame or opening as
the original glass it replaces; rubber molding is optional.
2. All window channels and window winding mechanisms may be
removed.
3. Closed cars: All side window glass may be removed. All rear
hatchbacks and deck lids shall be completely closed; poor alignment of bodywork or any other means to prevent complete closure
is not permitted.
4. Open cars: All windows and windshields (including windshield
frames) may be removed. The resulting window slots may be covered.
5. The installation of windshield safety clips, rear window safety
straps, and windshield safety straps is permitted.
L. The contour of the fender may be altered (flared) for tire clearance
provided the modifications do not confuse the identity of the car. Only
standard production ventilation openings on the specific recognized
model are permitted. Tires may extend beyond the bodywork. Fender wheel openings may be trimmed to provide tire clearance throughout the full range of suspension travel, but no more than is necessary
for this purpose.
M. Inner fender panels separating the wheel wells from the engine compartment may be altered, replaced, or removed. Rear inner fender
panels may be altered, replaced, or removed provided there are panels providing total separation between driver/ passenger compartment and wheels. A shock/strut tower integral to the inner fender
panel is considered part of the inner fender panel and is included in
this allowance. This does not allow modification of frame/frame stubs
beyond Section 17.2.C.
N. Replacement, addition, or removal of accessories (gauges, switches, indicators, etc.), or other interior modifications for driver convenience, or to permit installation of required safety equipment, is authorized provided such modifications have no influence whatever on
the mechanical performance of the car. Such modifications do not
include the substitution or replacement of any bodywork or chassis
component except those specifically authorized by these rules.
O. The standard OE front spoiler or a non-standard front spoiler may
be used. If a non-standard front spoiler is used it must comply with
the following requirements: It shall not protrude beyond the overall
outline of the car as viewed from above, or aft of the forward-most
part of the front fender opening (cutout) and shall not be mounted
more than four inches (4.0”; 101.6 mm) above the horizontal center17. Prepared Category — 119
line of the front wheel hubs. The spoiler shall not cover the normal
grille opening at the front of the car. An intermediate mounting device
may be used on cars whose front bodywork is above the four inch
(4.0”; 101.6 mm) minimum. Openings are permitted for the purpose
of ducting air to the brakes, radiator, and/ or oil cooler(s); equal openings may be placed in the standard lower front panel directly behind
openings placed in the spoiler.
P. A spoiler may be added to the rear of the car provided it complies with
either of the following:
1. It is a production rear spoiler which is standard or optional equipment of a U.S. model of the vehicle, or an exact replica in an
alternate material.
2. It is a non-production rear spoiler which is mounted to the rear portion of the rear hatch, deck, or trunk lid. The spoiler may extend no
more than ten inches (10.0”; 254 mm) from the original bodywork
in any direction. Alternatively in a hatchback, the spoiler may be
mounted to the rear hatch lid at or near the top of the hatch in
such a configuration the spoiler may extend not more than 7½
inches (7.500”; 190.5mm) form the original bodywork in any direction. The spoiler may be no wider that the bodywork. The use
of endplates is prohibited. Spoiler endplates are defined as any
vertical (or semi-vertical) surfaces attached in front of the spoiler
which have the result of capturing and redistributing air (downforce) along all or any portion of the spoiler. The angle of attack is
free. The spoiler may not function as a wing.
Q. The fuel tank may be modified, replaced, or relocated. If the fuel tank
is modified or replaced, the following restrictions apply:
1. No part of the fuel tank or fuel cell shall be closer than six inches
(6.0”; 152.4 mm) to the ground unless enclosed within the bodywork and mounted above the floor pan. A metal bulkhead is required that provides total separation between the driver compartment and the compartment containing the fuel tank and/or filler/
neck. This includes fuel tanks that are flush mounted with driver
compartment panels or otherwise exposed to the driver compartment. Fuel filler doors in the driver compartment must be positively
fastened (non-metallic fasteners are not allowed). For the purposes of these rules, a fuel tank consisting of a structure containing a
fuel bladder is considered to be the entire fuel cell, including the
containing structure. The containing structure of a fuel cell does
not qualify as a bulkhead. A separate metal bulkhead must isolate
the fuel cell from the passenger compartment.
2. Internal body panels may be modified to accommodate the installation of the fuel tank as long as such modifications serve no other
purpose. In the event installation includes encroachment into the
driver’s compartment, a metal bulkhead shall prevent exposure of
the driver to the fuel tank.
3. Fuel tank breathers shall not vent into the driver/passenger compartment.
R. All mirrors and their associated mounting hardware may be removed
or replaced.
S. The hood, hatchback, deck lid and fenders may be lightened or
replaced by ones of alternate material, provided the shape is similar to the original and does not confuse the identity of the vehicle.
Factory bolt-on fenders may be replaced in their entirety. Cars with
non-removable fenders may replace the front fender panels going
forward from the foremost door opening and the rear fender panels
going rearward from the rearmost door opening. Closed cars must
not remove stock material above the horizontal line placed at the
lowest point of the driver’s door window opening, with the exception
that OE removable panels (e.g., T-tops, targa tops, sunroofs) may
be removed or replaced with panels of alternate material provided
that the dimensions of any replacement panel do not vary from those
of the original by more than one inch (1”; 25.4 mm) in any direction.
The approval of alternate body panels does not authorize the use of
belly pans forward of the firewall or aft of the front edge of the rear
wheel opening. Ground effect tunnels and/or attempts to gain ground
effects are also not authorized. Any such elements incorporated in
the otherwise approved components must be removed or disabled.
Front hoods and engine covers may be vented and/or louvered. The
total area for all vents/louvers on a vehicle may not exceed 500 sq
in (3225.8 sq cm), unless provided as standard equipment. The total area is measured as the total open area or the perimeter of the
louvers when viewed from above. All openings must be covered with
a wire mesh having openings no greater than ½ inch (0.500”; 12.7
mm).
The location, number, and shape of vents/louvers is unrestricted provided they are fully contained on allowed panels. For vehicles having
original vents/louvers exceeding these dimensions, no further openings are permitted. Louver openings must face rearward and may
stand no higher than one inch (1.0”, 25.4 mm) above the original
surface. No additional scoops, cowls, bulges, or ducts are permitted
unless specified in Appendix A.
T. All headlights, front parking lights, and front signal lights may be removed. Headlight doors may be removed, replaced or modified. Any
remaining openings shall be covered with a wire mesh screen or
panel of fiberglass, Plexiglas, metal, or other nonflammable material. Ducts from headlights, headlight doors, front parking lights, and
front signal lights may be used for ducting air to the engine, front
brakes, and/or oil cooler(s). Any opening used for ducting may not
be relocated. These ducts may pass through interior panels for this
purpose. The cross section area of a single duct shall not exceed the
cross sectional area of the original (single) headlight.
U. All side marker lights and tail/stop lights may be removed. If such an
item is removed, the resultant opening must be covered.
V. Spare wheel and tire may be removed.

17.11 OTHER
A. Vehicles prepared in excess of Solo® allowances and prepared up
to either the current Club Racing GT or Production category rules
are permitted to compete in their respective Prepared classes. Section 17.8.B.7 minimum track requirements apply. Minimum weight
will be 110% of the Solo® minimum weight from Appendix A plus any
Solo® weight penalties (wheel size penalties, etc.). Vehicles taking
advantage of this allowance may use the Solo® Rules or the Club
Racing GCR (General Competition Rules) allowances in whole, in
part, or in combination. Cars which are not listed in the GCR may
not use this allowance and are limited to the modifications allowed
in Section 17. For those cars which have been de-listed from the
current year GCR, the appropriate specifications will be developed
and added to Appendix A upon member request. An exception to
the GCR will be that open cars are permitted, provided they comply
with all provisions of Section 17 pertaining specifically to open cars.
The following items listed in the GCR, while recommended, are not
required: Logbooks, annual inspections, roll cage, on-board fire systems, hand-held fire extinguisher, scattershield/chain guards, master
switch, steering wheel lock removal, window safety net, windshield
safety clips and rear window safety straps, and braided steel brake
lines. Single Inlet Restrictors (SIRs) are not required. Due to the extent of modifications permitted on GT-derived cars classed within the
Prepared category, it is possible for a replica car to meet the legality
requirements for the corresponding original model provided that the
engine, track, and wheelbase remain within the allowed specifications. In such a case the replica is considered legal for Prepared,
provided it correctly meets all of the applicable GCR specifications.
The 10% increase in minimum weight does apply to such cars.
B. Weight Calculations
Where there is a percentage addition as well as a specific weight addition, the percentage is added to the base weight before the specific
weight addition. Examples:
1. The minimum weight for a turbocharged 2.5 liter AWD car in class
X Prepared is:
1.4 X 2.5 = 3.5 X 250 = 875 + 1200 = 2075 lbs total
2. The minimum weight for a C Prepared car of 302 cubic inches,
prepared to 17.11 allowances, with 12” wide wheels is:
2700 lbs X 1.10 = 2970 lbs + 50 lbs = 3020 lbs total
C. Data acquisition/recording systems are permitted.
D. Except where there are specific requirements in these rules, any
safe line for fuel, hydraulic fluids, oil, water or breather is allowed.
E. Ballast may be added to all cars as required, to meet minimum weight,
provided it is securely mounted within the bodywork and serves no
other purpose. Ballast plates may be installed beneath the floor pan,
so long as they do not protrude beyond its edges.
F. All cars may have towing eyes, hooks, or straps, which do not dangerously protrude from the bodywork.
G. Removal of or modification to heating, ventilation, air conditioning,
washer/ wiper, audio, security, communication, and convenience
systems is allowed, provided the modification does not serve another purpose (e.g. an air conditioning compressor may not be modified
to serve as a supercharger).
17.12 SAFETY
A. Roll Bars/Roll Cages (Aluminum is not an allowed material.)
1. All open Prepared Category vehicles shall have at a minimum a
roll bar complying with Appendix C.
2. It is recommended that all cars be equipped with a roll cage meeting the requirements of the Club Racing GCR. Compliance with
this requirement supersedes the need to comply with 17.12.A.1.
3. Roll bars and cages may either be bolted or welded to the vehicle.
B. At a minimum all vehicles will be equipped with driver restraints
meeting Solo® Safety requirements. It is highly recommended that
all cars with roll bars/roll cages be equipped with driver restraints
meeting the requirements of the GCR.
C. A scattershield or explosion-proof bell housing complying with the
GCR is recommended.
D. Fire extinguishers or fire systems are permitted.

18. MODIFIED CATEGORY
Sports cars and sedans altered in excess of Prepared Category, sports
racing and two-seat specials, Formula cars, single-seat specials, dune
buggies and kit cars. Active Automatic Braking Systems (ABS) and
Traction Control Systems (TCS) are prohibited in Modified Classes B,
C, and F (BM, CM, and FM). Traction Control Systems are prohibited
in Modified Class A (AM). Active Automatic Braking Systems (ABS) and
Traction Control Systems are prohibited in Modified Classes D and E
(DM and EM), except for the original system installed on the car, which
may not be modified. Engine RPM limiting devices (rev limiters) are
allowed in all Modified classes. Data acquisition systems are allowed
in all Modified classes unless specifically prohibited by the applicable
GCR section(s).
Modified Category cars are divided into classes based on potential
Solo® performance. They need not be licensed for or capable of street
use. The Solo® Rules shall take preference over the Club Racing GCR
(General Competition Rules) concerning safety requirements for vehicles in this Category. Aerodynamic devices must be securely mounted
on the entirely sprung part of the car and must not be moveable when
the car is in motion. The use of any moving device (for example a fan,
propeller, or turbine) or hinged wing to create downforce is prohibited.
Movable side skirts are not permitted except where noted herein or in
Appendix A, Modified Category.
If a formula car or sports racer is restricted by a GCR-stated exhaust
length or vehicle length and therefore prohibited from installing the necessary exhaust devices to quiet the car to meet local dB limits, the following shall apply:
The vehicle exhaust system length may be extended to allow for the
installation of noise suppression devices. This allowance is provided
solely to reduce the exhaust noise emanating from these cars by allowing the installation of (a) noise limiting device(s) and in so doing
keep the total exhaust length to a minimum for safety reasons. The
installation and the noise limiting device(s) shall serve no other purpose
than that stated and this allowance only applies to an extension of the
exhaust system, not the vehicle bodywork or frame.
Engine Classifications
A.Four-stroke cycle and two-stroke cycle, naturally aspirated, internal
combustion engines will be classified on the basis of actual piston
displacement.
B.Rotary Engines (Wankel): These units will be classified on the basis
of a piston displacement equivalent to twice the volume determined
by the difference between the maximum and minimum capacity of
the working chamber, times the number of rotors.
C.Turbocharged or supercharged versions of the above engines will be
classified on a basis of 1.4 times the computed displacement.
18. Modified Category — 137
Aerodynamics
The area of a wing shall be computed by multiplying the width and
depth of the wing assembly (top view) without regard to the curvature and/or inclination of the wing or number of elements. Any airfoil
shadowed by another airfoil with more than six inches between them
will have its own projected area added to the wing area calculation.
Any diffuser-type aerodynamic device under the car which is used
in downforce generation is not included in the wing area calculation.
This specification supersedes Section 12.9 for these classes.
Tires
Any tire (including recaps) meeting the applicable portions of Section
3.3 is allowed.
Safety Rules
A.The following shall be required in all Modified Category vehicles:
1. Scattershields/Chain Guard - The installation of scattershields or
explosion-proof bell housings shall be required on all cars where
the failure of the clutch, flywheel, or torque converter could create
a hazard to the driver or passengers. Chain drive cars shall be
fitted with a protective case/shield to retain the chain in case of
failure.
The following material requirements apply to scattershields/explosion-proof bell housings:
0.125 inch SAE 4130 alloy steel
0.250 inch mild steel plate
0.250 inch aluminum alloy
NHRA or SFI approved flexible shields
2. Master Switch - All cars shall be equipped with a master switch
easily accessible from outside the car. Spec Racer Ford vehicles
shall be wired per RFSRII. The master switch shall be installed
directly in either battery cable and shall cut all electrical circuits
but not an on-board fire system, if so equipped. It shall be clearly
marked by the international marking of a spark in a blue triangle
and mounted in a standard location. OFF position shall be clearly
indicated at the master switch location. The standard locations
shall be as follows:
a. FORMULA AND SPORTS RACING CARS — In proximity to
the right-hand member of the roll bar, but in a location so that
it cannot be operated accidentally. It can be mounted on a
bracket welded to the inside of the upright member or mounted
so that the operating lever or knob is outside of the body panel
immediately inboard of the upright member.
b. CLOSED SPORTS RACING CARS, PRODUCTION CARS,
AND GT CARS - In front of the windshield on either the cowl
or on top of the fender, but close enough to the windshield to
be accessible if the car is overturned. Alternatively, it may be
mounted below the center of the rear window or on a bracket
welded, clamped or bolted to the roll cage or dash, easily accessible through the open window. (Drilling of holes in roll cage
to attach the bracket is prohibited.)
c. OPEN PRODUCTION and GT Cars - May exercise a choice
among the above locations.
3. Driveshaft Hoop - RWD DM and EM vehicles shall have a driveshaft hoop capable of preventing the shaft from entering the driver’s compartment or damaging any fluid or electrical lines in the
event of joint or shaft breakage. All cars in competition using open
driveshafts must have a retainer loop with 360° of enclosure, 1/4”
minimum thickness and 2” wide, or 7/8” x 0.065” welded steel
tubing, securely mounted and located so as to support and contain the driveshaft in event of U-joint failure. Vehicles that have a
closed “tunnel” or other such structure which the driveshaft passes through such as the vehicle’s frame, may be considered for an
exemption from the SEB if that structure meets the criteria stated
above.
NOTE: DM and EM vehicles are exempt from the scattershield,
driveshaft hoop, and Master Switch requirements if they are using
street DOT-approved tires.
4. The roll bar structure must meet the requirements of either Appendix C or the Club Racing GCR required by class rules. Roll
cages are strongly recommended.
“Specials” are required to have the roll bar extend at least two (2)
inches above the driver’s helmet in the normal seated position
and a head restraint keeping the driver’s head from going under or
behind the roll bar. It is strongly recommended that all cars adhere
to this specification.
5. Firewalls and floors shall prevent the passage of flame and debris to the driver’s compartment. For cars having fluid lines in
a non-stock routing over the belly pan, the belly pan shall have
drain holes to prevent the accumulation of fluids.
6. Ballast may be added to obtain minimum weight requirements.
However, it must be attached and secured in a safe manner.
7. Club Racing GCR specific items and/or equipment not required in
Modified Category are as follows:
1. Fuel cells.
2. Windscreens, side mirrors and tail/stop lights.
3. Headlight covers, lenses, and bulbs.
4. Log books.
5. Fire retardant fire driver’s suits.
6. Homologation.

10.The 180° vision rule is recommended.
11.Deformable structures as defined by the GCR Formula Atlantic
rules.
12.On board fire systems.
13.Reverse gear in BM and FM vehicles.
14.A front impact attenuation device (GCR 9.4.5.G) is not required
in Solo® Modified Category vehicles.
15.Driver restraint system aging requirements (GCR 9.3.18.G) do
not apply.
NOTE: If any conflict exists between the Club Racing GCR and
the Solo® Rules, the Solo® Rules shall take precedence.
Refer to Appendix A for additional class-specific vehicle preparation
rules.
The following types of cars are assigned to the Modified Category:
18.1 MODIFIED PRODUCTION-BASED CARS
A.Eligibility
Classes DM and EM contain production-based cars which are permitted additional modifications beyond those allowed in Prepared
classes CP through GP. Models must meet the requirements of Section 13 (first paragraph), be specifically listed in Appendix A, meet the
specifications below, or be otherwise recognized by the SEB.
1. Kit Cars
Kit cars, which were originally designed, constructed, and licensable for street use, may participate in DM and EM if they are approved by the SEB. Members desiring approval of a particular kit
car should provide the SEB with detailed information regarding
the kit model and contact info, if available, for the OE manufacturer. For obsolete kit cars, the member will be expected to provide
construction specifications, dimensions, and photographs for the
SEB to examine and keep on file. The SCCA® will evaluate each
submitted kit model individually, and the evaluation will ensure
that the specific model:
a. Follows current DM and EM allowances regarding minimum
floor pan dimensions (see 18.1.B.1.j).
b. Has no unusually advantageous aerodynamic features.
c. Has no exceptionally low center of gravity.
d. Has no exceptionally high strength to weight ratio.
e. Has no other unique features that would upset the competitive
balance in DM and EM.
f. Has independently-verifiable evidence of at least 10 examples
which meet the approved specification produced. Extremely
limited production sports racer-type efforts are discouraged.
Constructed examples of approved kits are subject to the following:
a. They will automatically take the Modified Tub weight penalty
(see Appendix A).
b.They will have the same weight/displacement scales and
weight bias penalties as production-based cars.
c. They will be allowed all the modifications that productionbased cars are permitted,
d. They are subject to the same engine/transmission restrictions
as production-based cars.
e. They must meet the same safety requirements as productionbased cars.
A newly-added model is not eligible for the current year’s Solo®
National Championships unless its listing was published no later
than the July issue of the official SCCA® publication.
The list of currently approved models is as follows:
(No models are currently listed.)
2.Clones
Clones/replicas of SCCA®-recognized production cars are permitted to compete in DM and EM, provided they comply with the
following requirements:
a. They are substantially similar to and recognizable as the ‘original’ manufactured vehicle on which they are based.
b. Their specifications do not violate any rule stated herein.
c. A clone shall not benefit from kit car manufacturer “running
changes” unless those changes have also been submitted and
approved.
3. Other Models
The Panoz Roadster is eligible for competition in DM and EM as a
modified production-based car.
4. Specifications
Weight and displacement specifications are as shown in Appendix
A.
B.Bodywork
1. Respecting Section 18.1.F - Aerodynamic Aids, bodywork may
be modified beyond the allowances of Section 17.2; however, the
shape of the body must remain recognizable as that of the approved make and model. The body must be made of a fire resistant material. Doors, hoods, trunk lids, sunroofs, hatchbacks, etc.
need not function as originally designed. Bumpers, grilles, lights,
glass, and trim may be removed. Side mirrors and tail/stop lights
are not required.
2. Firewalls and floors shall prevent the passage of flame and debris to the driver compartment. For cars having fluid lines in a
non-stock routing over the belly pan, the belly pan shall have
drain holes to prevent the accumulation of fluids.
3. The driver must be provided with clear and unobstructed access
to the driver’s compartment.
4. Interiors may be gutted. The driver’s seat must be securely
mounted. Steering and driver seating must be completely to the
left or right of the vehicle longitudinal centerline. The seat must
be mounted such that no part of the driver’s body below the waist
may cross the longitudinal centerline of the car.
5. Body panels may be altered and air ducting installed to accommodate the installation of the water radiator. If the radiator encroaches into the driver compartment, it must be separated from
the driver by a metal bulkhead or enclosing container.
6. Hoods may be altered to allow for induction system changes
without restriction. Such alterations shall serve no other purpose.
7. Standard bumpers may be retained, removed, or bumpers may
be made of alternate materials. The bumper, if retained, will contribute its contour to the top view outline of the car for measurement purposes. Bumpers made of alternate materials shall retain
the shape and size of the original.
8. Doors may be replaced with ones of alternate materials. No
other part of the original outside bodywork between the original
passenger compartment fore and aft bulkheads, such as rocker
panels, floor pan, or frame, shall have reduced thickness or be
replaced with lighter material.

or step between the driver’s compartment and the engine or
main luggage area.
c. In cars where a rear luggage compartment is not totally closed
off from the passenger compartment, the base of the floor pan
step or base of a part-height panel that would limit rearward
travel of the rearmost of seat bottoms is the rear bulkhead
point. If there are built-in seat track catches or stops, they are
assumed disabled for this definition of travel.
d. Heavier gauge material repairs or heavier replacement sections are all allowed as long as they closely resemble the original.
e. No removal of the interior sides of the pillars or tub to leave just
an outer shell.
f. Interior storage compartment doors, luggage/trunk compartment panels, parcel shelves may be modified or removed.
g. Wheel wells and bulkheads are open to modification as long
as the driver is protected from fire and debris.
h. Floor pan width must match or exceed that between the insides of the original rockers. Length must be matched between
the original passenger compartment bulkhead locations. Floor
pan is defined in Section 12.7. Longitudinal structure such as
rockers may not cover or overlap the floor pan width. The full
stock floor pan width or greater must be visible when viewed
from directly above for at least the length of the door openings.
The floor pan may only be cut for drivetrain/exhaust/tire/suspension clearance.
i. Tunnels and other vertical floor pan features as defined in Setion 12.7 are included as part of the floor pan of a stock tub and
shall be at least the original size. They can be longer, wider,
and taller.
j. No car of any sort with a floor pan less than 37” wide for frontengine cars or less than 42” wide for mid- and rear-engine cars
shall be allowed in DM or EM.
k. A Stock Tub car over 93” in wheelbase may change its wheelbase and remain a Stock Tub car if the stock rear bulkhead
location and floor pan length are retained.
No weight adjustment.
2. Modified Tub
a. All attributes of a stock tub must be maintained in this category
except as explicitly allowed below. There is a weight adjustment associated with a modified tub.
b. A modified tub is one that mainly achieves a lower CG and
improved strength to weight ratio.
c. Lightweight replacement body panels, a thinned-down stock fiberglass body, or a lift-off lightweight shell attached to the main
body structure are examples of a modified tub when done in
the bulkhead-to-bulkhead region.
d. Vertical features above the bottom floor pan plane do not have
to satisfy original minimum size or shape. Note that the original
width and length of the floor pan still have to meet the original
dimensions. Drivetrain tunnels and seat mounting platforms
may be made smaller than stock, with a Modified Tub weight
adjustment. A flat floor pan is legal.
e. Floor pan material and thickness are open under Modified Tub
allowances.
f. Rear passenger doors, if present, may be replaced with nonfunctional panels. Front and rear doors and door openings may
be altered to accommodate compliant wheelbase changes.
g. All other cars, Stock or Modified Tub, whose factory wheelbase are less than 93” may still change their wheelbase, but
it must be done without violating the floor pan length as determined by both front and rear factory bulkhead locations.
h. All series of Lotus 7, 7A, Super 7, and their clone or kit forms
such as Birkin, Westfield, Locost, are automatically classified
as modified tubs. This also applies to the Cobra and its clones.
i. Tube frame cars are included in this tub category.
3. Materials (all tubs)
a. Ferrous (containing iron) metal must be used for all primary
load-bearing structures of the car. The primary load bearing
structure is the main tub or chassis and its connections to the
suspension. No aluminum cages or roll bars are allowed. Any
ferrous or aluminum alloy is permitted for suspension arms,
location links, and uprights/spindles. Beryllium and beryllium
alloys are not allowed anywhere on the car.
b. The exceptions to the above are parts of the donor production
cars that were originally non-metal. In all cases, replacement
of these parts or addition of more load bearing structure must
be by metal. Lighter replacement sections may not be used
between bulkheads in a stock tub without it becoming a modified tub.
c. Lightweight substitute materials such as carbon fiber are permitted only so long as they are clearly not load bearing in the
primary structure or the suspension. For example: outer body
panels in the central tub region must be attached in a flexible manner such as with Dzus fasteners if non-stock material
composition or non-stock material thicknesses are to be used.
d. Cars that have been approved for DM and EM as clones do
not have the freedom to use better strength per weight structural materials than those originally used in the corresponding
places in the originals. The only exception is the use of high
carbon or chromemoly steel in place of mild steel.
D.Drivetrain
1. Engines must be derived from production automobiles available
in the US or elsewhere. Complete race engines derived from
production automobile block designs such as the Pontiac Super
Duty 4 and the Cosworth 16-valve series are allowed. Motorcycle,
snowmobile, marine, or any other initially non-automotive design
is not allowed even if it was also made available in an automobile.
Non-automotive engines are prohibited. 4-stroke automotive motors shall not be converted to 2-stroke.
2. Engine and/or drivetrain changes are permitted within the following limitations:
a. Original front-engine design must remain a front-engine design (i.e., no part of the engine block or cylinder head may
extend rearward of the midpoint of the wheelbase).
b. Original rear- or mid-engine designs may be interchanged with
each other, but no part of the engine block or cylinder head
may extend forward of the midpoint of the wheelbase.
3. Non-automotive CVTs are prohibited. Automotive-based CVTs
are only allowed with their matching factory engine.
4. Internal and external components of the engine, transmission,
and rear differential are unrestricted. Any shifting mechanism or
pattern is permitted. Driveshafts may be made of any material
deemed safe. Supercharging and turbocharging are permitted
without restriction but shall require the displacement specifics of
Section 18.
5. For weight designations in EM, Mazda rotary engines are compared to the piston engines listed (i.e., 3.2L OHC vs. 4.5L OHV).
13B rotary engines should be equated to the 3.2L OHC engines.
13B forced-induction rotary engines (1308cc x 2 x 1.4 = 3662cc)
and all 3-rotor engines shall be grouped with vehicles required to
meet the stated 1800 lb. minimum weight.
E.Minimum Weights
Minimum weights for cars in DM and EM and all adjustments to these
weights are shown in Appendix A.
F. Aerodynamic Aids
1. These classes are restricted downforce classes. No aerodynamic
tunnels, wings, or sealing skirts may be added. No bargeboards,
ramps, vanes, wickerbills, or other aerodynamic devices are allowed except as specified.
2. The hood, tub, roof, rear fenders, and rear deck are not permitted
to be reshaped to achieve downforce. The front of the car may be
reshaped to accommodate the construction of spoilers, air dams,
and splitters, and may be widened to rear body width as specified
in Section E.4.c below. Ramps joining the front fender flares to
the splitter/spoiler/airdam assembly which are included as part of
a SCCA®-approved GT-1 front bodywork package are allowed.
3. Front Aero
a. The standard OE or a non-standard front spoiler or air dam
may be used. A non-standard front spoiler is not permitted
to protrude forward beyond the overall outline of the car as
viewed from above or aft of the forward most part of the front
fender opening and shall not be mounted more than four inches above the horizontal centerline of the front wheel hubs.
b. The spoiler may cover the normal grille opening at the front of
the car. Cooling duct openings are permitted. If the front radiator is removed or relocated, no aerodynamic use of the unobstructed front radiator pathway may be made. The front spoiler
may be attached to the original bodywork or it may replace the
bodywork it would otherwise cover.
c. The front spoiler may be no wider than the rear bodywork,
measured as in Section E.4.c. below. The front spoiler may not
function as a wing, and therefore must be installed such that
air does not pass both over and underneath it. This may be
accomplished by ensuring that the upper edge of the spoiler
is in complete continuity with the bodywork above the spoiler.
New bodywork may be added to close the gaps between the
fenders, nose, and spoiler/splitter/airdam assembly on cars
with open or irregular front bodywork such as the Ford Model
T, MG TD, Morgan, and Lotus Seven. When these or similar
vehicles use a full-width front spoiler, the car’s spoiler/airdam
is required to be vertical (between 80-100°) for the lower 8”
of its extent. The change in top view outline caused by these
bodywork changes is allowed.
d. Front splitters are allowed but must be installed parallel to the
ground (within +/- 3/16 inches fore to aft). Splitters may not be
wider than, nor extend more than 6” forward of the top-view
outline of the car.
4. Rear spoilers
a. If a rear spoiler is used, it shall be mounted to the rear hatch,
deck, or trunk lid, and mount no further forward than the base
of the rear window. The spoiler extension for the entire spoiler
is set by one measurement at the lateral midpoint of the car.
At that point, the spoiler may not extend more than 10” from
the attachment point out to the outer or free edge. This sets
the maximum height above ground at all other locations on the
spoiler. The result may be a flat topped rather than contoured
spoiler. Alternatively, the spoiler may be mounted at the rear
of the roof, or to the rear hatch lid at or near the top of the
hatch; in such a configuration the spoiler may extend no more
than 7.5” from the original bodywork, measured as described
above. The spoiler angle of attack is free. The rear spoiler is
measured from leading, attached edge to trailing or outermost,
free edge. Its measurement is independent of its angle of attack.
b. The spoiler may not be wider than the rear bodywork, measured as the maximum distance between the outside edges of
the wheel well openings or fender flares at axle height.
c. Aerodynamic aids permitted in Section 18.1.E shall not function
as wings. Therefore, the spoiler may not overhang the bodywork such that air passes both over and underneath it. If the
rear spoiler overhangs the side of the car, the lower edge of
the spoiler shall be supported by bodywork that will prevent
air from passing underneath the spoiler. This may be accomplished by extending the spoiler to join the bodywork or wheel
opening/fender flare beneath the overhang.
5. Diffusers are allowed at the rear of the car only and shall have
no more than 25” front to back of expanding chamber. Vanes or
strakes are allowed inside the diffuser. A diffuser is defined as an
expanding chamber between the vehicle and the ground for the
purpose of accelerating air ahead of it to develop low pressure.
The diffuser may protrude rearward beyond the top view outline
of the car. Closed undersides or belly pans (lower surface) are
permitted. The entire length of the underbody may be closed off
to permit proper airflow to a rear diffuser or to smooth the underside of the car. The belly pan shall be flat within 1 inch total
deviation. No tunnels or other underbody aerodynamic features
are permitted. Chassis rake is free. Additionally, no side skirt or
body side, etc., may extend more than 1 cm below this lower surface anywhere on the car to the rear of the front axle unless specifically permitted by these rules. Diffuser sideplates and strakes
may extend below the diffuser surface as long they do not attain
a definite seal with the ground on level ground.
6. If the factory production car was supplied with tunnels or wings,
they may remain, but they must be blocked in a safe manner
to prevent them from functioning to provide downforce. For example, foam or sheet metal may be firmly attached in tunnels or
on wings to ruin their shape or to stop airflow.
7. The use of front and rear spoiler endplates is allowed. Endplate
area shall not exceed spoiler height squared. A roof spoiler up to
the maximum of 7.5” is allowed an area of up to 16 square inches
for each endplate; a trunk spoiler up to the maximum of 10” is
allowed up to 100 square inches for each endplate. Side plates
do not have to be square or rectangular; the side profile shape is
open. If end plates are to be used with the front spoiler/air dam/
splitter assembly, a maximum area of 36 square inches per end
plate is allowed.
G.Brakes
The use of any type brakes, pads, and components are permitted
(disc or drum). The location of brake components (inboard vs. outboard) may be changed from original. The original “emergency” or
hand brake may be removed.
H.Tolerances
A tolerance of ±½” shall be used when measuring floor pan dimensions from the car’s original specifications.
I.Other
1. At least ½ the width of each tire must be covered by the fenders, when viewed from the top of the fender perpendicular to the
ground. No sharp edges are permitted.
2. Suspension systems and wheels are free.
3. The use of a windscreen is not required.
4. Roll bar requirements for cars competing in DM and EM are as
specified in Section 3.3.2.

19. KART CATEGORY
If a modification is not specifically authorized in this or previous applicable sections of the Solo® Rules, it is not allowed.
Data acquisition systems are allowed in all kart classes.
See Appendixes G and H for event conduct requirements.
19.1 KART MODIFIED (KM)
A. FRAME/DIMENSIONS
1. Chassis must be constructed of carbon steel alloy using traditional tubular construction. Nerf bars are required. Suspensions
are prohibited. Differential mechanisms that allow the rear wheels
to rotate at different speeds are prohibited.
2. Maximum width measured at any point shall be 55 inches. Maximum length measured at any point shall be 84 inches.
3. All karts shall have bodywork consisting of a nose cone, driver
fairing, and side-pods. (Full width nose pieces are recommended.) Bodywork may not extend past the rear nerf bar. No metal
bodywork is allowed (although metal number plates to allow use
of magnetic numbers are permitted). Belly pans are allowed provided that they are fully confined within the frame rails and do not
extend aft of the leading edge of the rear axle. No skirts or vertical aerodynamic sealing devices are allowed to extend below the
main frame rails (this does not include the front fairing). No wings
allowed.
4. Minimum weight for entrants in 125cc shifter karts is 385 lbs as
raced, including driver, regardless of driver gender or class entered. Weights for entrants with karts having other engines are as
listed in Section 19.1.D.3.
5. All non-structural weights must be affixed to the kart, seat, or driver in such a way as to prevent said weight from becoming separated from kart/driver or moving freely during competition runs.
For bolted-on weights, a 5/16” (8 mm) Grade 5 or higher bolt must
be used along with a locking nut, pinch nut, double nut, or safety
wire. No more than 5 lbs of weight per bolt may be used. In addition to bolted-on weights, this also allows weights to be placed
on the driver underneath a suit, to be placed inside the seat liners/inserts, and to be used with quick change mechanisms, thus
facilitating addition and removal of weight during driver changes.
Arm or wrist weights are prohibited. Ballast weights may not be
mounted to nerf bars or moving parts.
B. WHEELS AND TIRES
1. Wheels must be metallic. Five and six inch (5” and 6”) rim diameters are approved.
19. Kart Category — 153
2. Tires
a. Tires must be no larger than 12.5” in diameter and no smaller
than 9.0” in diameter as imprinted on tire. Tire width is limited to
5.5” for the front and 7.1” for the rear as imprinted on tire.

must not appear on the following list, which may be altered at
any time by the SEB upon notification of membership:
C. BRAKES
1. Moto and ICC 125cc Shifter Karts: Moto and ICC shifter karts must
have disc brakes that operate on all four wheels. The brakes shall
be a dual system, arranged in a manner to provide braking for at
least two wheels in the event of failure in part of the system.
2. Other Allowed Karts: Other karts that are allowed to compete in
KM (see 19.1.D.3 below) may use a braking system that complies
with the rules to which the kart is prepared (e.g., WKA, IKF, Stars
of Karting series). The competitor is responsible for providing the
rules to which the kart is prepared (i.e., an 80cc shifter or 100cc
clutch type is not required to have front brakes). All karts with engine configurations other than moto/ICC 125cc, that are allowed
to compete in KM, must have at a minimum, a single rear disc that
brakes both rear wheels equally and adequately for the powerplant used. The addition of front brakes is optional.
3. A “brake safety cable” or redundant brake pedal connection is required in all karts.
D. ENGINE
1. Moto: Engines must be mass-produced, single cylinder, motocross
motorcycle engines up to 125cc displacement and of the current
year’s production or older. No prototype, preproduction, “works
type motors,” or road race engines are allowed. Engines may be
liquid or air-cooled. Induction may be piston port or case reed type
only. OE parts can be interchanged from any year model of the
same brand name and similar model of motor (i.e., CR to CR, YZ
to YZ, etc.), provided that these parts are normally commercially
available over the counter in the USA to all competitors.
a. Bore/Stroke: Bore must not exceed 1mm (0.040”) greater than
the stock, factory dimension. Stroke must be within plus or minus 0.010” of the stock, factory dimension.
b. Carburetion: One carburetor, single-venturi, float bowl type.
Twin pump floatless recirculation systems are allowed. Pumpertype carburetors and axle/electric fuel pumps are not allowed.
Intake manifold and reed assembly are unrestricted. Must use
pulse-driven fuel pump.
c. Crankshaft/Connecting Rod: Crank and Rod Assembly must be
OE components. No structural modifications may be made to
the assembly (i.e., the machining, boring, or polishing of counter balances or rod, machining for the purpose of weight reduction, heavy metal balancing, altering crank pin location) are
expressly prohibited. Sanding or polishing the crank shafts or
bearing journals for the purpose of allowing a slip fit of the bearings is allowed. The two main bearings, big end bearing, and
small end bearing are not tech items.
d. Cylinder and Cylinder Head: The cylinder and/or head, including ports, power-valves, and castings, may be modified or machined subject to the requirements of Section 19.1.D.1.e. Water inlets and/or outlets may be modified for aftermarket fittings
and/or hoses. Adding or deleting cylinder ports or re-sleeving
is not allowed.
e. External Modifications: All exterior engine components (e.g.,
cylinders, heads, case halves) must remain recognizable as
OE parts. Kick starter assembly may be removed and plugged.
The kick start boss may be altered to facilitate the use of a
straight intake manifold. However, evidence of the original kickstart boss must be obvious. Machining of the reed block/intake
boot mounting boss on the case that reduces the original distance between the outer surface and the piston (reducing intake tract) is not allowed.
f. Ignition:
1. OE ignition: Only OE ignition components for specific
engine(s) are allowed, except that spark plug, spark plug
cap, and plug wire are unrestricted. Modifications (i.e., rewinding, alteration of permanent magnets, etc.) to stator
and flywheel are not allowed. EXCEPTION: Modifications to
change the static timing are allowed in all Moto engines. Origin of spark coil is unrestricted, but it may not possess any
function which serves to alter ignition timing.
2. Non-OE Ignition: Non-OE Capacitive Discharge Ignition
(CDI) may be used provided that the stator, rotor, and flywheel (including any wires and connectors) must be OE and
may not move by any remote device. Furthermore, the ignition system may not control the fuel induction system in any
manner. Ignition interrupt systems (e.g., speed shift and no
lift shift systems) are specifically disallowed. The CDI must
be normally commercially available over the counter in the
USA to all competitors. Use of any non-OE ignition CDI, programmable or pre-programmed, incurs a 25 lb weight penalty.
g. Exhaust Systems: Exhaust system is unrestricted. No “oncourse” adjustment of exhaust system is allowed.
h. Piston Assembly: Piston assembly is open, including piston,
ring, wrist-pin, and circlips. Coatings are allowed.
i. Transmission: OE cases must be used. Transmission gear sets
are exchangable within a manufacturer’s engine series as an
update/backdate allowance. This does not allow substitution
of gears with those from another manufacturer or aftermarket
parts. Shifter mechanisms must be manually operated, no air
or electric assisted shifters are allowed.
j. Clutch: A wet-type clutch must be used. All components must
be in full and original working order. The clutch inner and outer
basket & pressure plate must be OE. Lightening of the clutch
assembly by machining or grinding is allowed. Springs, discs,
and plates may be “aftermarket parts.” Clutch may be operated
by either cable or hydraulic cylinder but must be manually operated. No electronic or pneumatic clutch controls allowed.
2. KZ (ICC): All current or prior approved CIK/FIA engines are allowed. Engine must be a liquid-cooled, single-cylinder, 125cc design with a single reed-valve circuit. All engine, intake, exhaust,
ignition, and transmission components must be CIK/FIA homologated except where otherwise specified. However, components
may be interchanged between model years of the same engine
manufacturer and brand. Karts with ICC engines must conform to
chassis, braking, wheel, and tire regulations of the Section 19.1
and incur an additional 25 lb weight adjustment.
a. Cylinder: Polishing, grinding, and cleaning of the port area are
allowed. Resurfacing of cylinder mating surfacing surfaces is
allowed. Reed block, reed cage, and reeds are open. No ports
may be added. Total exhaust duration must not exceed 199°.
b. Cylinder head: Machining of the cylinder head is allowed. Combustion chamber volume must be at least 13.4cc as measured
with the LAD tool.
c. Induction: Air box is required and must meet current or prior CIK
homologation. The carburetor must meet current or prior CIK
homologation and not exceed 30.6mm maximum bore.
d. Exhaust pipe: Pipe must be CIK homologated for the brand of
engine being used as supplied by the manufacturer. The CIK
homologation stamp must be present on the pipe.
e. Exhaust silencer: Make and manufacturer are open spec. Silencer must meet sound requirements.
f. Transmission: Transmission components must be standard
parts. This means if an aftermarket part is substituted, it must
be of similar dimensions as the original part. The weight of the
replacement part will not be less than the standard part. The
outside diameter and tooth count of the replacement gears
must be the same as the standard part. Grinding or polishing
transmission parts to provide a better mesh is allowed.
g. Ignition: Ignition must be CIK homologated for the brand of engine being used as supplied by the manufacturer.
h. Spark plug: Spark plug must be standard, commercially available spark plugs. The body of the spark plug (electrodes not
included, tightened on the cylinder head) must not extend beyond the upper part of the dome of the combustion chamber.
Dimensions:18.5mm length, 1.25 thread pitch. NOTE: This is
checked with gasket or temperature sending unit in place.
i. Crank, rod, and flywheel: Crank, rod, and flywheel assembly
must be standard components. No modifications will be made
to the assembly. Therefore, the machining, boring, or polishing of counter balances or rod, machining for the purpose of
weight reduction, heavy metal balancing, or altering the crank
pin location are all expressly prohibited. Sanding or polishing
the crankshafts or bearing journals for the purpose of allowing
a slip fit of the bearings is allowed. The two main bearings, big
end bearing, small end bearing, piston, piston pin, ring, and
clips are all non-tech items.
j. Cooling: An electric water pump may be added to allow circulation of coolant while stationary. The pump, battery, and associated plumbing shall serve no other purpose.
k. Shifting: Mechanical gearbox control only. No ignition interrupt
systems allowed.
3. Other Engines: Engines must be either a) mass produced single
cylinder two-stroke engines not to exceed 125cc or b) mass produced single or twin cylinder, four-stroke engines not to exceed
250cc of total displacement. No prototype, preproduction, “works
type” motors or road race engines are allowed. Shifter or gearbox
type motors are prohibited. Karts with engines under this specification must run at a minimum weight of 360 lbs. EXCEPTION:
The engine must not appear on the following list, which may be
altered at any time by the SEB upon notification of membership:

APPENDIX A - AUTOMOBILE CLASSES
It is the intention of SCCA® to class all essentially identical vehicles
from the same manufacturer (which differ only cosmetically or in nominal marquee designation) in the same class. If a version is omitted from
the class listing, and is otherwise eligible for the category, then its classification will be the same as the equivalent car which is listed.
All unclassified cars will compete in Super Stock (SS) until classified by
the SEB, unless covered by a “catch-all” description. To use the catchalls at the end of the specific car classes in Appendix A, start from Super Stock (SS) and work down the classes until a class is found. Such
unclassified cars will not be eligible for Solo® National Tours or
the Solo® National Championships. Members should look for a
Tech Bulletin in an early current-year issue of the official SCCA®
publication (Fastrack® News) for details or contact the National
office.
See the following page for vehicles which are excluded from the Stock
category.
For Stock Category vehicles, the vehicle manufacturer’s specifications
shall be used for specific wheel diameter and maximum rim width specifications.
ABBREVIATIONS:
AWD - All-wheel drive
FWD - Front wheel drive
IRS - Independent rear suspension
NOC - Not otherwise classified
N/A - Normally aspirated
RWD - Rear wheel drive

STREET MODIFIED CATEGORY
Engine Classifications
1. Four-stroke cycle and two-stroke cycle, naturally aspirated internal combustion engines will be classified on the basis of actual
piston displacement.
2. Turbocharged or supercharged versions of all engines will be classified on a basis of adding 1.4L to the actual displacement.
3. Rotary Engines (Wankel): These units will be classified on the
basis of a piston displacement equivalent to 0.9 liters times the
number of rotors, plus the volume determined by the difference
between the maximum and minimum capacity of the working
chamber times the number of rotors.
4. Electric Motors: Cars with electric motors, in whole or part of the
drivetrain, will run at class maximum weight of 2900 lbs for SSM
class and 3100 lbs for SM class. Category weight adjustments
(e.g., tire size) are allowed.
Weight Adjustments
Cars running tires with a rated width of 275 mm or less on all four
wheels may compete at a minimum weight 200 lbs less than their
calculated weight.

will NOT receive the weight adjustment as stated in the SM class.)
PREPARED CATEGORY
Prepared Class X (XP)
XP vehicles must conform to the rules in Section 17 except as noted
herein. This class is for almost any production car using almost any
automotive drivetrain. Any vehicle meeting the requirements of 17.A.2,
listed in another Prepared class in Appendix A, specifically listed in CP,
DP, EP, FP, or GP that is not required to run at 17.11.A specified weights
or listed below is eligible for XP. 17.11.A does not apply. “In-excess”
cars per 17.11.A are not eligible for XP.
1. BODYWORK AND STRUCTURE
a. Chassis components attached by removable fasteners (e.g. bolt-on
subframes) may be modified or replaced without penalty.
b. Front hoods, engine covers, trunk lids, hatches, front fenders, rear
fenders not part of chassis structure (unibody), front & rear fascias,
and side skirts may be modified or replaced, and may be attached
with removable fasteners. Associated hardware including latches,
hinges, and window washer nozzles may be modified, removed, or
replaced. Fenders may be flared as per Prepared (17.2). Unibody
fender may be replaced as described in 17.2.S. Non-metallic fender
liners may be modified, replaced, or removed. Body panels may be
attached with removable fasteners (e.g. Dzus).
c. Aerodynamic Aids: Wings may be added, removed, or modified. NonOE wings may only be attached to the rear deck/hatch area behind
the centerline of the rear axle. The total combined surface area of
all wings shall not exceed 8 square feet as calculated per Section
12.9. The number of wing elements is limited to 2. Wings designed
to be adjustable while the car is in motion must be locked in a single
position.
Canards are allowed and may extend a maximum of 6 inches forward of front bodywork/fascia as viewed from above. No portion of
the canard may extend past the widest part of the front bodywork/
fascia as viewed from above. Canard area will be measured in the
same manner as wings using section 12.10. Canard area may not
exceed 15% of the total wing allowance. The sum of canard area and
rear wing area may not exceed the total wing allowance.
Wings, and any component thereof, may not extend beyond the vehicle width, as defined by the outermost portion of the vehicle doors,
less mirrors, door handles, rub strips, and trim. In addition, no portion
of the wing or its components may be more than 6” forward of the
rear axle, more than zero inches (0”) beyond the rearmost portion of
the bodywork, or more than six inches (6”) above the roofline of the
vehicle, regardless of body style. Reinforcements to the wing mounting area may be used, but may serve no other purpose.
Wing endplate surface area is limited to 200 square inches each

a tunnel/cover of an alternate material.
g. The shift lever opening in the body of the car may be altered to allow
the installation of alternate shift linkage.
2. WHEELS
Any size wheel may be used. Wheel size does not affect minimum
weight.
3. SHOCK ABSORBERS & SPRINGS
a. Section 17.5.G, which restricts the type of shocks authorized by
17.5.C, does not apply.
b. Active/reactive suspension systems incur a minimum weight adjustment, including standard parts.
4. BRAKES
Anti-lock braking systems (ABS) may be added, replaced, removed, or
modified. The use of ABS including original equipment incurs an ABS
weight adjustment. ABS providing traction and/or stability control in any
form will also incur a traction/stability control weight adjustment.
5. SUSPENSION CONTROL
Any front and rear suspension system type (MacPherson/Chapman
strut, double A-arm, live axle, etc.) may be used.
6. ELECTRICAL SYSTEM

transverse, longitudinal stays longitudinal).
d. Any traction or stability control systems are permitted, but incur a
minimum weight adjustment, including standard parts.
e. Air may be ducted to the induction system. Openings in the bodywork
to allow air to be ducted are allowed provided they serve no other
purpose.
8. OTHER
Vehicles exceeding these rules and prepared to the Club Racing GCR/
GTCS or GCR/PCS are not eligible for this class.
9. MINIMUM WEIGHTS
a. Engine Classifications
1. Four-stroke cycle and two-stroke cycle, naturally aspirated, internal combustion engines will be classified on the basis of actual
piston displacement.
2. Turbocharged or supercharged versions of all engines will be classified on a basis of 1.4 times the actual displacement.
3. Rotary Engines (Wankel): These units will be classified on the
basis of a piston displacement equivalent to twice the volume determined by the difference between the maximum and minimum
capacity of the working chamber, times the number of rotors.
b. Minimum Weight Calculations
All listed weights are without driver. All weights are calculated based
on displacement as listed per Appendix A, 10.a. Example: Weight for
a 1837cc RWD car is 1200 + (1.837 x 200) = 1567 lbs.
Engine displacement less than 4.0L
Engine displacement of 4.0L or greater
Regardless of the weight formulas above, no car shall be required
to weigh more than 2300 lbs before applicable weight adjustments.

Note: BP is not a National-level class. All vehicles currently classed
in BP are eligible for XP under Section 17.0.A.2, provided the vehicle
complies with the XP preparation allowances. Competitors are reminded that XP does not allow vehicles that take the “in-excess” weight penalty under 17.11 or that have floor or firewall modifications previously
allowed in the BP section of Appendix A. These cars may be required to
run in their appropriate Modified class.
** indicates Induction: one four-barrel carburetor restricted to 1-11/16”
throttle bore or fuel injection.
Engine Coolant flow direction is unrestricted.
U.S. produced 6-cyl & 8-cyl engines are allowed alternate-stroke crankshafts; crankshaft angles must remain standard.
U.S. produced 6-cyl & 8-cyl engines manufactured by a particular corporation may be interchanged with ones of similar configuration from
the same corporation (e.g., a Chevrolet engine would be allowed in a
Pontiac). Corporate engine substitutions include induction systems and
thus no weight penalty is incurred for using the OE induction from the
substituted engine.
Similar configuration is defined as having the same number and arrangement (i.e. V, Straight, Flat, etc.) of cylinders and camshafts (e.g.
Dual Overhead). Displacement changes are allowed. Alternate engines
for a particular model must locate the bell housing to block mounting
surface in the same plane as the standard part.
Alternate iron or aluminum cylinder heads may be used on U.S. produced 6-cyl & 8-cyl engines. Any alternate cylinder head(s) used shall
be of a conventional design (siamesed intake ports, 2v per cylinder, all
valves inline) direct replacement type.
Vehicles using Mazda rotary engines, which are currently permitted to
use 13B engines, may alternatively use the Renesis RX-8 engine.
The floor in the driver/passenger compartment may be replaced but
must maintain the basic shape and position of the original floor; i.e.,
flat and horizontal, relative to the car and rocker panels. It may not be
curved, angled, recessed, or channeled between the rockers and may
be made of steel and/or aluminum only. Replacement floors may be
modified per 17.2.E.
The firewall between the engine compartment and driver/passenger
compartment may be replaced but must be in approximately the same
location as the original and must create a sealed bulkhead between
engine and driver/passenger. Replacement firewalls may be made of
steel and/or aluminum only and may be modified per 17.2.F.
An alternate hood is allowed which has a bulge no more than four inches, measured off of the original base model hood, for induction clearance.
The bulge may open to the front, rear, or to either or both sides. If the
original base model hood has a 2 inch bulge, then an addition of 2
inches is allowed, if the base model has a 3 inch bulge, then 1 inch is
allowed, etc. There is no allowance for non-standard heat extraction
vents.
Wheel size allowances are as per 17.4
Minimum weights are determined from the following tables according to
engine type and displacement. The block may bored and/or sleeved to
achieve allowed displacement.

Wheel size allowances are as per 17.4.
Weight formulas (lbs):
Piston Engines: 0.75 x displacement (cc)
Rotary Engines: 0.70 x listed displacement (cc)
Forced Induction: +0.450 x displacement (cc)
Peripheral Port Rotary: +0.050 x displacement (cc)
AWD: +0.100 x displacement (cc)
FWD: - 0.100 x displacement (cc)
Weight Adjustments: Equipment, Weight (lbs)
Regardless of the weight formulas above no car may weigh less
than 1900 lbs or be required to weigh more than 2700 lbs prior to
addition of weight adjustments defined herein and in Section 17.
Weight Calculation Example
Subaru STI (2.5L) running 11” wheel width
Actual displacement (before overbore): 2457cc
The formula would be: 0.75 (piston engine) + 0.375 (forced induction) + 0.075 (AWD) = 1.2 (total weight factor).
Calculated weight: 1.2 x 2457 = 2948 lbs (exceeds maximum limit).
2500 lbs (maximum calculated weight) + 100 lbs (wheel width over
10” weight adjustment) = 2600 lbs (total competition weight).

round-slide carburetors. AMW powered cars may use either the 38
mm AMW carburetors or update to the 38 mm Mikuni round-slide
carburetors. In order to accommodate the use of the approved
Mikuni VM 38mm sidedraft carburetors on the AMW engine, the
use of the AMW intake manifold (part #2736-00) is permitted as
are the AMW rubber attachment boots, gaskets, and/or hardware
required for the use of this manifold. Competitors using the Rotax
494 RAVE engine are required to use the 494 non-RAVE rotary
valve (Rotax part #924509 or 924508, Ski Doo prefix 420, 147 degree designation that opens @ 135 degrees BTDC and closes @
64 degrees ATDC) in their engine. RAVE valves shall be blocked
in the ‘full open’ position or left as delivered. No other alterations
are permitted. 494 RAVE and non-RAVE parts may not be interchanged between the two engines unless specifically noted.
6. Competitors utilizing the Rotax 493 engine may leave the manufacturer’s specified intake balance tubes in place or, at their option, completely remove the tubes and make the alterations required to plug the remaining holes. No unnecessary alterations
are permitted if the competitor chooses to remove the tubes. The
Rotax 493 engine is limited to a Y-pipe exhaust manifold and single expansion chamber as are the Rotax 494 and AMW engines.
7. F5 cars may utilize the Rotax 593 engine, 1999 and up (bore: 76
mm; stroke: 65.8 mm) using 38mm Mikuni roundslide carburetors

minimum weight with driver of 850 lbs. Such engines must use
inlet tract restrictors (Cometic gasket #MA0242SP1020A), one in
each tract immediately after the carburetor. Use of the 2003 and
up “HO,” “SDI,” “RS,” and “E-TEC” 593 variants is not permitted.
8. All F440 & F500 engines may use any water thermostat. It may be
modified or completely removed as necessary to aid water cooling. The water bypass may be blocked and alternate water cooling
plumbing may be used. Electric water pumps may be used.
9. F440 & F500 cars in FM are not required in Solo® to have the
sidepods now mandated by Club Racing if they were manufactured prior to 1984 in which that requirement was added to the
GCR. Sidepods may not be removed from a car which was originally manufactured with them. The measurements for the height,
the maximum width (bodywork), and the distance from the tires of
sidepods as specified in the GCR, Bodywork E.9 2nd paragraph,
shall have an allowance from the GCR of +/- one inch. It is the
intent of this allowance to maintain the ability of the sidepod(s) to
continue to hold such items as fuel tanks, battery, and radiator(s),
but not to allow sidepods to be used for ground effects to achieve
aerodynamic downforce on the vehicle.

NOTE: If any conflict exists between the WSDCA or US Legend Cars
Rules and the Solo® Rules, the Solo® Rules shall take precedence.
Cars prepared to these specifications are required to comply with the
appropriate rules from their sanctioning body, except for the items
listed below:
Any tire (including recaps) meeting the applicable portions of Section 3.3 are allowed.
Any differential and final drive ratio may be used.
Any shock absorber may be used.

APPENDIX B - BUMPING ORDER
“Bumping” is not approved for championship events. However, the following bumping order is recommended for regional events in cases where a
class is to be combined with another class.
The progression of the ladies bumping order shall be: if there is only one
competitor in a Ladies Class, that competitor shall move to the parallel
Open Class. If a class is still not formed, the competitor should then be
bumped into the next appropriate Ladies Class (see diagram). If a class
has still not been formed, the competitor should again be bumped to the
appropriate Open Class. This movement would continue until a class is
formed.
Example: HSL entrant(s) bump to HS, then HSL entrant(s) to GSL, then
HSL entrant(s) to GS, then HSL entrant(s) to DSL, etc. Also, Ladies Class
entrants should be bumped first to create a class. Example: If there is only
one entrant in each of the three classes CS, DS, and DSL, the entrant in
DSL would be bumped into DS first to form a DS class and the CS entrant
would then be bumped upward into BS (i.e., it would not be correct to
bump the DS entrant into CS before considering the DSL entrant).
Proceed left to right following the arrows, until a class is formed. Where
two bumping paths come together (including Ladies-to-Open bumps), all
bumps up to the joining point should be done before continuing along the
bump path.

APPENDIX C - SOLO® ROLL BAR STANDARDS
A. BASIC DESIGN CONSIDERATIONS
1. The basic purpose of the roll bar is to protect the driver in case the
vehicle rolls over. This purpose should not be forgotten.
2. The top of the roll bar shall not be below the top of the driver’s helmet
when the driver is in normal driving position, and shall not be more
than six inches behind the driver. It is strongly suggested that the
roll bar extend at least three inches (3”, 76.2mm) above the driver’s
helmet. In case of two-driver cars, both drivers must be within the roll
bar height requirement, however only one (1) driver must be within
six inches (6”, 152.4mm) of the roll bar. In a closed car or an open car
with a removable OE hardtop which is equipped with a roll bar/cage,
it must be as close as possible to the interior top of the car.
3. The roll bar must be designed to withstand compression forces resulting from the weight of the car coming down on the roll structure,
and to take fore-and-aft loads resulting from the car skidding along
the ground on the roll structure.
4. The two (2) vertical members forming the sides of the hoop shall not
be less than fifteen inches (15”, 381mm) apart (inside dimension).
It is desirable that the roll bar extend the full width of the cockpit to
provide maximum bearing area in all soil conditions during rollovers.
The roll bar vertical members on formula cars and other single seat
cars with a center driver position must be not less than fifteen inches
apart, inside dimension, at their attachment points to the uppermost
main chassis member.
5. An inspection hole of at least 3/16 inch (0.1875”, 4.75mm) diameter
must be drilled in a non-critical area of a roll bar member to facilitate
verification of wall thickness. This should be at least three inches (3”,
76.2mm) from any weld or bend.
6. It is recommended that steel gusset plates be used at all welds. Gussets should be at least two inches (2”) long on each leg and 3/16
inches (0.1875”, 4.75mm) thick.
7. It is recommended that roll bars be coated only with a light coat of
paint. If, however, a roll bar should be chrome-plated, it is recommended that the structure be normalized.
8. Post or tripod types of roll bars are not acceptable.
B. MATERIAL
After 9-22-85, aluminum is not an acceptable alternate material. Cars
using aluminum roll bars or roll cages must file proof with SCCA® Technical Services that the structure was approved prior to 09/22/1985 as
provided in this section.
1. The roll bar hoop and all braces must be of seamless ERW or DOM
mild steel tubing (SAE 1010, 1020, 1025) or equivalent, or alloy steel
Appendix C - Roll Bar Standards — 241
tubing (SAE 4130). It is strongly recommended that roll bars not be
constructed of ERW due to quality and strength concerns.
2. The size of tubing to be used shall be determined on the basis of the
weight and speed potential of the car. The following minimum sizes
are required and are based upon the weight of the car without the
driver.
Vehicle Weight (lbs)
Tubing Size (minimum)
outside diameter x wall thickness (in)
Over 1500
1.500 x 0.120
1.750 x 0.095
1000 - 1500
1.250 x 0.090
Under 1000
1.000 x 0.060
Dimensions are nominal. 0.005” (0.127mm) variation in wall thickness is allowed.
3. Each mounting plate shall be at least 0.080” (2.03mm) thick if welded
and 3/16” (0.1875”, 4.75mm) thick if bolted. A minimum of three (3)
bolts per plate is required for bolted mounting plates.
4. All bolts and nuts shall be SAE Grade 5 or better and 5/16” (0.3125”,
7.94mm) minimum diameter.
C. FABRICATION
1. One continuous length of tubing must be used for the hoop member
with smooth continuous bends and no evidence of crimping or wall
failure.
2. All welding must be of the highest possible quality with full penetration and will be subjected to very critical inspection. Arc welding, particularly heliarc, should be used wherever possible.
D. BRACING
1. It is recommended that braces be of the same size tubing as used
for the roll bar itself.
2. All roll bars must be braced in a manner to prevent movement in
a fore-and-aft direction with the brace attached within the top onethird of the roll hoop, and at an angle of at least thirty degrees from
vertical. It is strongly recommended that two such braces be used,
parallel to the sides of the car, and placed at the outer extremities of
the roll bar hoop. Such braces should extend to the rear whenever
possible.
3. It is suggested that roll bars include a transverse brace from the bottom of the hoop on one side to the top of the hoop on the other side.
E. MOUNTING PLATES
1. Roll bars and braces must be attached to the frame of the car wherever possible. Mounting plates may be used for this purpose where
desired.
2. In the case of cars with unitized or frameless construction, mounting
plates may be used to secure the roll bar structure to the floor of the
car. The important consideration is that the load be distributed over
as large an area as possible. A backup plate of equal size and thickness must be used on the opposite side of the panel with the plates
through-bolted together.
F. REMOVABLE ROLL BARS
Removable roll bars and braces must be very carefully designed and
constructed to be at least as strong as a permanent installation. If one
tube fits inside another tube to facilitate removal, the removable portion
must bottom on the permanent mounting, and at least two bolts must be
used to secure each such joint. The telescope section must be at least
eight inches in length.
G. INSTALLATION ON CARS OF SPACE FRAME AND FRAMELESS DESIGN
It is important that roll bar structures be attached to cars in such a way
as to spread the loads over a wide area. It is not sufficient to simply attach the roll bar to a single tube or junction of tubes. The roll bar must
be designed in such a way as to be an extension of the frame itself, not
simply an attachment to the frame. Considerable care must be used
to add as necessary to the frame structure itself in such a way as to
properly distribute the loads. It is not true that a roll bar can only be as
strong as any single tube in the frame.
H. ROLL CAGES
It is recommended but not mandatory that all cars utilize a roll cage as
defined in the applicable section of the Club Racing GCR.
I. ROLL BAR PADDING
Braces and portions of the main hoop subject to contact by the driver’s
or passenger’s helmet, as seated normally and restrained by seat belt
and harness, must be padded with a non-resilient material such as
Ethafoam® or Ensolite® or other similar material with a minimum thickness of one-half inch (½”, 12.7mm).
Appendix C - Roll Bar Standards — 243
APPENDIX D - SOLO® TRIALS RULES
I. PURPOSE
Solo® Trials provides a venue for SCCA® members who wish to experience higher speeds than the current Solo® program allows and/or
for whom the Time Trials program has not been available or desirable.
Solo® Trials is a program for regions and drivers with a lower level of
speeds, hazards, administrative complications and costs than Time Trials.
Background Motivation:
Several independent and marque autocross clubs, although considerably less regulated, have offered this type of program for many years
without competition from SCCA®. Since region and member input indicated a need SCCA® has developed this new program. An added incentive to formulate this program for our membership was the potential
to attract new members from the independent clubs who run this type
of event into the SCCA® Solo® Program.
The Solo® Trials Program has three primary goals:
1) to be a venue for our members to compete in a safe, higher speed
Solo® event;
2) to give SCCA® Regions, previously unable for various reasons to
conduct Time Trials, a different type of Solo® event to offer current
and potential members; and
3) to develop a cadre of new competitors and organizers experienced in
Solo® Trials events who will be encouraged to consider involvement
in Time Trial Events. With the achievement of these three goals the
Solo® Trials Program will provide a more rounded Solo® program
for our members.
II. CONCEPT
The Solo® Trials Rules specified within this Appendix are an extension
of the Solo® Rules. They are exception or additions to those rules and
as such, if a subject matter is not specific herein, the Solo® Rules governing that matter shall also govern a Solo® Trials event.
All Solo® Trials Events will generally be run on flat, expansive asphalt
or concrete pavement with very minimal fixed objects present on the
course site. Essentially, these events will be planned for sites such as
airport facilities or very large parking areas that can have a defined
perimeter to control access and be protected from unwanted entry. This
program is not intended for racetrack facilities, which are used for Time
Trials events or shopping mall-type parking lots that are commonly
used for Solo® events. Extremely rare exceptions may be made for
racetrack facility usage under special circumstances when the course
design and locations of hazards present appropriate risks, such as an
airport-based facility.
The course will be designated by pylons, and as in other Solo® events,
displacement of these pylons will penalize drivers.
Solo® Trials events can be characterized as introductory Time Trials
events, using pylon defined road courses and speeds in excess of
those currently limited in the Solo® program are permitted but are more
limited than for Time Trials events. Approved course designs will not
normally permit potential vehicle speeds of the fastest Stock, Street
Touring®, or Street Prepared vehicles to exceed 95 MPH.
Solo® Trial events will fall under the authority of the Divisional Solo®
Steward (DSS) and under the regulation of the National Solo® Rules
(SR), except as exempted by these Solo® Trials Rules.
III. PROCEDURE FOR SCCA® SANCTION
Regions wishing to participate in the Solo® Trials Program shall comply
with the following:
- Submit to the SCCA® National Office an event site approval, if applicable, and request for sanction which includes a proposed scale
course design map with surrounding areas indicated.
- All new sites are required to have an inspection to determine suitability
for this program. Prior approved sites do not need any subsequent
inspections as long as there have been no changes to the surface
or other safety-related attributes since the initial inspection. Sanction
will be granted after successful completion of course site inspection.
IV. SITE SELECTION AND COURSE DESIGN APPROVAL
Courses shall be placed on relatively level, smooth pavement surfaces
and shall avoid incorporating elevation changes or abrupt high-speed
maneuvers that could lead to loss of control.
The course design should limit straights (defined as a section of course
where full acceleration is possible, regardless of whether it is totally
straight or not) to a maximum of 1,200 feet, including the braking zone
preceding a subsequent maneuver. The intent of this requirement is
for the top speed of the fastest Solo® Stock, Street Touring®, or Street
Prepared-type cars to not normally exceed 95 mph at any point on the
course.
The course shall be designed to provide the Chief Steward and the
Safety Steward, or their designated representatives, a direct line of
sight to all portions of the course or radio communications must be
provided between all corner stations and those officials.
Prior event site inspection is mandatory and shall be coordinated with
the Solo® Safety Committee (SSC). The inspection shall be made by
the Divisional Solo® Safety Steward (DSSS) or a designated representative of the SSC. This inspection will ensure that:
1. The proposed course pavement and overall event facility is capable
of supporting a safe event;
2. Proper worker safeguards are available and will be utilized; and
Appendix D - Solo® Trials Rules — 245
3. The event site can be appropriately secured from unwanted entry by
unauthorized individuals.
A safety report on the acceptability of the site shall be filed with the SSC
with copies to the SCCA® National Office. This report shall form the basis of SCCA® sanction and insurance issuance. Once a course site has
been approved, it need not be inspected again unless there have been
changes in pavement or to surrounding course areas. However, each
subsequent event must go through all other sanction requirements.
V. SCCA® INSURANCE
Liability and Participant Accident coverage will be provided as indicated
in the SCCA® Insurance Manual
VI. EVENT OFFICIALS
The Chief Steward and Safety Steward shall be appointed by the Solo®
Chairman of the host Region but may be subject to review by the DSS
and/or the DSSS if there is a need. All other officials may be appointed
by the host Region without review.
All event officials must be SCCA® members in good standing. The selection of the Chief Steward and the Safety Steward shall be done with
utmost care reflective of the type of event. It is recommended that the
Chief Steward and Safety Steward have Time Trials experience but, as
a minimum, these officials shall have five (5) years Solo® experience
as an Event Chairman or a Safety Steward.
VII. ENTRANT ELIGIBILITY AND LICENSING
Drivers must be an SCCA® member, at least 16 years old, and possess a “full privilege” operator’s (driver’s) license from their state of residence.
Novice drivers may not participate in any Solo® Trials event. Drivers in
a Solo® Trials event must have experience in at least four (4) parking
lot-type Solo® events within the last two (2) years. Proof may be in the
form of event results or a letter from a Regional Executive, Divisional or
National Solo® Official attesting to the experience level of the prospective entrant.
VIII. WORKERS
Events will operate primarily utilizing competitors, who are not competing at the moment, as course workers. This practice will duplicate the
procedures currently in place for the Solo® Program. However, it is
highly recommended that experienced Club Racing Flagging and Communications workers be used in a supervisory capacity. Prior to the
beginning of competition runs, a workers training session will be held in
order that each worker (driver) be familiar with what will be expected of
them when they are placed on station.
IX. EVENT SAFETY REQUIREMENTS
1. A fire vehicle shall be provided that will be equipped to fight car fires.
This vehicle must carry a minimum of 60 pounds total capacity dry
chemical fire extinguisher(s).
2. An ambulance must be on call and available to respond within five (5)
minutes of a telephone call from the event site. A cellular phone must
be available on site to minimize response time in the event of an
emergency. At a minimum, one (1) individual certified in Advanced
First Aid by the American Red Cross, or equivalent, along with an extensively equipped First Aid, kit must be present and available. If this
individual is also a competitor, another certified individual must be on
duty while he or she is competing. It is highly recommended that an
ambulance be stationed on site and staffed with qualified personnel
for the duration of the event.
3. A prearranged safety plan, approved by the SSC, must be in place to
cope with major emergencies.
4. At least 20 lbs of dry chemical extinguisher (total capacity) must
be provided at each flagging station. Each station shall also be
equipped, at a minimum, with a red and a yellow flag.
5. Radio communication shall be provided from each flagging station to
event officials at the event control point.
6. At a minimum, each station shall have two workers.
7. Each flagging station shall be on the inside approach of its respective
corner and be placed a minimum of 75 feet from the course edge.
It is highly recommended that the station be located behind a solid
protection barrier such as, but not limited to, concrete, tire wall, or
Armco.
X. VEHICLE SAFETY EQUIPMENT REQUIREMENTS
A vehicle safety inspection conducted in accordance with Solo® Rules
Section 3.3.3. must be successfully completed prior to competition.
Competitors and officials are reminded that this inspection must be conducted with consideration to conditions of a Solo® Trials event. The
Chief Steward is authorized to prevent any vehicle from competing that
he or she believes to be inadequate. In addition, vehicles must meet the
following applicable requirements:
1. Vehicles prepared to Club Racing specifications must meet all current GCR safety equipment requirements.
2. Vehicles prepared to Time Trials specifications must meet all current
Time Trials safety equipment requirements.
3. Vehicles prepared to Solo® specifications must meet the following
additional requirements:
a. Street Modified, Prepared and Modified category vehicles, and
all open vehicles, must have a roll bar meeting current Solo® Appendix C standards (Exception: Open cars may substitute factory hardtops equipped with bolt-in fasteners). In addition, Stock,
Street Touring®, and Street Prepared vehicles whose owners
wish to install, or are required to have, or currently have a roll bar
must have a diagonal brace on the roll bar. The brace may be removable but must be the same size/dimension as the tubing used
for the hoop and be attached at the highest possible point on one
vertical leg of the roll bar and the lowest possible point of the other
vertical leg of the roll bar. Bolt-in roll bars are permitted. It is highly
recommended that all Solo® prepared vehicles have roll cages/
roll bars meeting current Club Racing GCR requirements. Roll
cages are highly recommended for all vehicles and, if installed,
must conform to the current GCR.
b. All drivers in SCCA®-sanctioned Solo® Trials events in which a
roll bar or roll cage is installed shall utilize either a five-, six-, or
seven-point restraint harness meeting the following specifications.
A 7-point restraint harness is recommended. Arm restraints are
required on all open cars including open targatops, sunroofs, and
T-tops. The restraint system installation is subject to approval by
the Chief Technical and Safety Inspector.
A. A 5-point system for use in automobiles where the driver is
seated in an upright position consists of:
1. A 3-inch seat belt or an FIA or SFI 16.5 certified 2-inch seat
belt.
2. An approximately 3-inch shoulder harnesses or FIA or SFI
16.5 certified 2-inch shoulder harnesses only if the HANS
Device is used by the driver. Should the driver at anytime
not utilize the HANS Device, 3-inch shoulder harnesses are
required.
3. An approximately 2-inch anti-submarine strap. A 5-point harness is considered a minimum restraint system. 6- or 7-point
systems are highly recommended in all cars including automobiles where the driver is seated in an upright position.
B. A 6- or 7-point system recommended for use in all automobiles
consists of:
1. A 3-inch seat belt or an FIA or SFI certified 2-inch seat belt.
2. An approximately 3-inch shoulder harness or FIA or SFI 16.5
certified 2-inch shoulder harness only if the HANS Device is
used by the driver. Should the driver at anytime not utilize
the HANS Device, 3-inch harnesses are required.
3. 2 or 3 approximately 2-inch leg or anti-submarine straps.
C. The shoulder harnesses shall be the over-the-shoulder type.
There shall be a single release common to the seat belt and
shoulder harnesses. When mounting belts and harnesses,
it is recommended that they be kept as short as reasonably
possible to minimize stretch when loaded in an accident. The
shoulder harness shall be mounted behind the driver and sup248 — 2012 SCCA® National Solo® Rules
ported above a line drawn downward from the shoulder point
at an angle of 20° with the horizontal. The seat itself or anything added only to the seat shall not be considered a suitable
guide. Guides must be a part of the roll bar/cage or part of the
car structure. Only separate shoulder straps are permitted (Ytype shoulder straps are not allowed). H-type configuration is
allowed.
D. The single anti-submarine strap of the 5-point system shall be
attached to the floor structure and have a metal-to-metal connection with the single release common to the seat belt and
shoulder harnesses.
E. The double lag straps of the 6- or 7-point system may be attached to the floor as above for the 5-point system or be attached to the seat belt so that the driver sits on them, passing
up between his/her legs and attaching either to the single release common to the seat belt and shoulder harnesses or attaching to the shoulder harness straps. It is also permissible for
the let straps to be secured at a point common to the seat belt
attachment to the structure, passing under the driver and up
between his/her legs to the seat belt release or shoulder harness straps. All straps shall be free to run through intermediate
loops or clamps/buckles.
F. Each seat belt and shoulder strap of the harness (5-, 6-, or
7-point) shall have an individual mounting point (i.e., 2 for each
seat belt and 2 for each shoulder strap minimum). 6- or 7-point
system anti-submarine straps may share a mounting point with
one or both seat belts. The minimum acceptable bolts used
in the mounting of all belts and harnesses are SAE Grade 5.
Where possible, seat belts, shoulder harnesses, and anti-submarine straps should be mounted to the roll structure or frame
of the car. Where this is not possible, large diameter mounting
washers or equivalent should be used to spread the load. Bolting through aluminum floor panels, etc., is not acceptable.
G. Unless specifically mentioned herein, compliance with all driver
restraint systems that comply with SFI 16.1, SFI 16.5, or FIA
8853/98 is highly recommended.
H. Harness threading must be assembled in accordance with the
manufacturer’s instructions. Tech Inspectors are cautioned to
inspect all belts and harnesses for wear, looking for abrasions,
rips, tears, or other issues which would make a belt/harness of
questionable value for its intended purpose. Vehicles with such
issues will be prohibited from these events.
Stock, Street Touring®, and Street Prepared category vehicles not
equipped with a roll bar or a roll cage may not use an upper body
restraint system other than the factory system.
c. A hand-held fire extinguisher adhering to the following standards
is highly recommended:
1. Halon 1301 or 1211; 2-pound minimum capacity by weight.
2. Dry chemical; 2-pound minimum with a positive indicator showing charge. Chemical: 10BC UL rated – potassium bicarbonate
(Purple K) recommended; 1A-10BC UL rated multipurpose –
ammonium phosphate and barium sulfate or Monnex.
3. The fire extinguisher shall be securely mounted in the cockpit.
All mounting brackets shall be metal and of the quick-release
type.
4. 125cc shifter karts are permitted with the appropriate driver safety
gear as specified in the Solo® Rules. However, depending upon surface irregularities of the site, the DSSS may prohibit these karts.
Formula Junior karts are not permitted.
XI. DRIVER SAFETY EQUIPMENT REQUIREMENTS
The following equipment must be displayed for Tech Inspection and be
used during competition by all drivers:
1. A helmet meeting the current Solo® requirements as a minimum.
2. All open cars and closed cars that do not have original equipment
roll up windows must be equipped with a window net or the driver
must wear an approved arm restraint system. Vehicles with original
equipment roll up windows may compete without either a window net
or a driver arm restraint if the driver side window is rolled up during
competition.
3. Drivers of open cars shall wear goggles or face shields.
4. SCCA®-compliant fire resistant clothing as listed in the current Club
Racing GCR is highly recommended for drivers of Solo® Street
Modified, Prepared and Modified category vehicles, and Club Racing
GT, Production, Formula, and Sports Racing vehicles. This includes
suits, gloves, socks, and shoes. Fire retardant clothing is highly recommended for all drivers.
5. All drivers must at a minimum wear 100% cotton (no blends) outer
wear that effectively covers the body from neck to ankles and wrists.
All drivers must wear shoes that cover the entire foot.
APPENDIX E - SOLO® SAFETY STEWARD GUIDEBOOK
I. INTRODUCTION
The Solo® Safety Steward (SSS) program is an ongoing training and
licensing program aimed at increasing the safety of SCCA® Solo®
events by highlighting the potential hazards of uncontrolled spectator viewing areas, uncontrolled spectator movement adjacent to Solo
courses, and driver/worker safety relative to course design or layout. It
is the intention of the SCCA® that all material contained herein is reviewed with all students during a Solo® Safety Steward Seminar.
Since a major concern of this program is with spectator safety, the first
important item to address is the definition of “spectator.”
There are two groups of people that attend our events, non-participants
and participants. Non-participants are those individuals that have not
signed the SCCA® waiver and participants are those individuals that
have signed the waiver. The words “Non-Participant” and “Spectator”
can be interchangeable, as can the words “Participant” and Driver,
Worker, Crew, or Guest.
Therefore, for the purpose of the Solo® Events program, a spectator is
a non-participant and a casual observer that may be interested in viewing a Solo® event. A driver, worker, crewmember, or guests are participants. A SSS has the responsibility and authority to require that these
individuals not be allowed to congregate in areas surrounding the actual course that would place them in jeopardy from competing vehicles.
The vast majority of Solo® events are sanctioned and insured as “nonspectator” events. Therefore, any non-participant lingering on the event
premises for more than a few moments must sign the SCCA® waiver
or leave the facility. However, such casual observers are common so
their safety and your protection must be addressed. Although is imperative that event waivers be signed, it is not the responsibility of the
Safety Steward to execute this function. This responsibility lies with
the event Chairman, who must reasonably assure that all participants
and non-participants sign the required SCCA® waiver. However, it is
the responsibility of the Safety Steward to confirm that the Chairman,
the Waiver Chief, or his/her designee is actively pursuing the SCCA®
waiver requirement.
Participant and non-participant safety is accomplished by establishing
safe viewing areas and then controlling these areas through the use of
physical barriers or the deployment of event workers as Crowd Control Marshals. It is a reality that participants and non-participants will
typically congregate in areas adjacent to the course “where the action
is.” Unfortunately, these action areas may also be the most dangerous
because individuals rarely realize the danger they place themselves in
when viewing a competition event. So they must, in effect, be protected
from themselves as is reasonably possible. Further, it is important that
it be understood that they can be very determined and will use every
Appendix E - Solo® Safety Steward Guidebook — 251
available means to accomplish their goal. A SSS must be constantly on
the alert and prepared to act upon potential hazardous situations.
The benefit to be derived from non-participant and participant control
at Solo® events is not limited to safety alone but reaches out to other
areas of concern for SCCA®. It seems to be a fact of life that insurance
premiums continue to rise on a yearly basis. Just as individual personal
insurance policies are subject to rate increases, so are the insurance
policies of SCCA®. The principle manner in which these rate increases
can be held to a minimum is by reducing the overall exposure to the
policy. Reduced exposure of the SCCA® policy equates to stable premiums. This reduced exposure can be the result of safe event management.
SCCA® Solo® events have an excellent safety record and it is important that it be kept that way. Therefore, the purpose of the SEB in initiating the SSS program was twofold:
1) to improve overall event safety and
2) thereby stabilize insurance costs.
II. START OF THE SSS PROGRAM
In the spring of 1976, the SEB reviewed the procedures used to control spectator-viewing areas. Previously, the efforts of SCCA® toward
safety had been primarily directed at the competitors, IE: personal
safety equipment, vehicle safety equipment, and course safety design.
Because of the potential for non-participant injury resulting from an offcourse excursion of a competition vehicle, it became clear that greater
emphasis should be placed on the establishment of safe viewing areas
and the control of these areas during our events.
A SSS Sub-Committee was formed and, with the assistance of insurance company representatives, a training program began that would
result in the licensing of SCCA® members in the specialty of spectator
control.
Initially, the training program was aimed at Solo I® events and championship Solo® events. However, because the growth of the Solo® program had resulted in increased spectator numbers at regional events,
the Safety Steward program was expanded to include every Solo®
event sponsored by an SCCA® region.
With the success of the Safety Steward program established, the SEB
approved a recommendation to expand a Steward’s area of responsibility and authority to include driver and worker safety relative to course
design. A SSS must now assure that Rule 2.2 “Course Safety and Layout Rules” is being properly followed for Solo® events and that driver
and worker safety, per the SCCA® approved event site plan, is being
followed for all Solo® events. As with all recommendations made by
a Steward for spectator safety, recommendations made for driver or
worker safety must be addressed to the satisfaction of the Steward.
Failure of the host region to make adequate corrections may initiate
procedures for cancellation of the event for safety reasons and event
insurance withdrawal.
Every Solo® event must have a licensed SSS on duty at all times. Since
this is necessary for insurance coverage, failure to meet this requirement will void the host region’s insurance for the event.
III. DIVISIONAL SOLO® SAFETY STEWARD
The Divisional Solo® Safety Steward (DSSS) is responsible for the
training and license recommendations (new or upgrades) of members
in his/her division. Further, since it is mandatory for all Solo® regions to
have a Safety Steward in attendance at their events, it is the responsibility of the DSSS to make sure that this requirement is being fulfilled.
IV. APPOINTMENT OF SSS FOR SOLO® EVENTS
The appointment of a SSS for regional Solo® events is the responsibility of the Regional Executive of the host region or his/her designee. In quite a few regions, this authority for regional Solo® events is
transferred to the Region’s Solo® Chairman and this is an acceptable
practice.
The Solo® Safety Committee (SSC) appoints the SSS, and deputies
as required, for all National Solo® Championship events, subject to the
approval of the Solo® Events Board (SEB).
The event manager will appoint the SSS for National Tour and ProSolo® Events. The hosting region normally suggests candidates.
V. PROCEDURES FOR BECOMING A SSS
A. SSS Licensing Requirements
There are two grades of Solo® Safety Steward licenses.
1. SOLO® SAFETY STEWARD
2. SOLO® SAFETY INSTRUCTOR
B. Interested members, 18 years of age or older, should communicate
with the DSSS of their division or their Regional Safety Steward/Instructor, expressing a desire to become a SSS. An application will be
forwarded to the member, or the member can obtain the application
from an instructor at a classroom seminar or at the SCCA® web site
(www.scca.com).
This application must be completed and returned to the DSSS following the completion of the training requirements.
C. Complete the SSS training. Training involves two phases:
1) Seminar (classroom) instruction; Seminar instruction is mandatory
for all members wishing to obtain a license and must be given by
a qualified Safety Steward authorized by the SSC as an Instructor.
2) Practical instruction; Act as assistant (Deputy or logbook holder)
to a licensed Safety Steward at two separately sanctioned Solo®
events.
D. The DSSS may, based upon the qualifications of the applicant, approve the license application. The Central Licensing Department
shall be advised of each approval and will issue each license.
E. Following an initial one-year licensing as a SSS, SCCA® Member
Services shall issue a renewal application every three (3) years,
pending completion of the appropriate number of events and continuing education as a Solo® Safety Steward. All requests for such
renewals shall be made by submitting a renewal application with the
appropriate number of events and the continuing education class
date recorded in the application. During each three-year licensing
period, the SSS must participate in one (1) continuing education
seminar and serve as a SSS at five (5) events. The DSS shall be responsible for confirmation of participation in the continuing education
process. The renewal date is the same as membership renewal. Effective 1/1/2011, all SSS must complete the requirements for 3-year
licensing not later than two (2) years after initial licensing.
F The requirements pertaining to licenses may be waived by the SSC,
except for the attendance at a seminar. Continuing education requirements for SSSI may be satisfied by attending a SSS seminar
conducted by another instructor or conducting one seminar each
year.
VI. PROCEDURES FOR BECOMING A SSS INSTRUCTOR
A. Members that are licensed SSS may obtain an application from their
DSSS or the SCCA® web site (www.scca.com/solo).
B. The application must be completed and sent to the DSSS along with
a letter of recommendation from an SEB member, a Director, an instructor who has worked with the applicant, or the applicant’s Regional Executive.
C. The DSSS may, or may not, approve the application and he/she will
forward it to the SCCA® National Office for distribution to the SSC.
The SSC will approve/deny the application based on the following
criteria:
1. The applicant must have at least two years experience as a licensed SSS.
2. The applicant must have officiated as a SSS in at least five events
in the past two years.
3. The applicant must have received a positive letter of recommendation from his/her DSSS.
These requirements may be waived on an individual basis by the SSC.
Instructor licenses will be automatically renewed when the member’s
SSS License is renewed each year unless the SSC instructs the National Office otherwise.
VII. SOLO® EVENTS AT RACING FACILITIES
With the dwindling availability of parking lot sites, some regions have
utilized racetracks. Go-kart tracks have been used quite successfully
by Solo® regions and, on occasion, so have some road racing or stock
car racing tracks. Unfortunately, road racing and stock car racing tracks
usually offer hazards that are sometimes overlooked by the local region
or, for that matter, by our Safety Stewards.
The word “hazard” is specifically mentioned in our rulebook because it
is the word we use to define what is acceptable to the Solo® program
from a safety standpoint and what is not.
Solo® Rules Section 2.1 states in part that “... hazards must not exceed those encountered in legal highway travel.” At many race facilities where the racing surface is used for a Solo® event, there usually
are guardrails, concrete walls, fences and/or other structures in close
proximity to the intended path of competing vehicles. If proper course
design has not been followed, an incident may take place that can, at a
minimum, result in vehicle body damage.
Our competitors are rarely, if ever, asked to perform maneuvers such as
slalom during normal highway driving. When we do ask them to negotiate such a maneuver at a parking lot Solo® event, we do so in an environment where they won’t injure themselves or damage their vehicles
if they fail to complete that aspect of the course. Simply put, there is
nothing around for them to hit if they lose control of their vehicle.
Section 2.2 states in part that “The course boundary shall not pass
closer than 25 feet from solid objects” (walls, guard rails, fences, buildings, poles). It should be noted that racing surfaces at most racetracks
are not much wider than 30-35 feet and normally do have solid objects
on their pavement edges. Therefore, in such situations where we ask
competitors to perform Solo® maneuvers; we may provide the potential
for having “hazards” that could exceed those that would be encountered under normal highway travel.
While race facilities are very well designed for the safety of workers and
spectators, the track itself is usually not well designed for Solo® events.
In order to maintain top speeds within the acceptable range for Solo®,
it is necessary to slow cars down with maneuvers such as offset gates
or slaloms. Two problems occur with this. One is that the usually narrow track affords very little runoff room between the course (i.e., edge
of a gate or pylon) and the edge of the pavement. Worse, often the
edge of the track at a road racing facility is an Armco barrier or cement
wall. Secondly, the two typical situations arising in the effort to maintain
Solo® type speeds are the placement of pyloned maneuvers just as
vehicles reach dangerous speeds (resulting in the potential for cars to
get out of control at high speed) or the overabundance of pylons in an
effort to keep speeds low resulting in a “busy” and unpleasant course.
One approach to solving this dilemma is to control the exit speed of
turns rather than the entrance.
Whatever solution is chosen, these problems must be dealt with carefully by experienced Solo® Officials, in order to successfully meet the
challenge of designing a safe and fun Solo® course on a racetrack.
VIII. RESPONSIBILITIES OF A SSS
A SSS is responsible for non-participant and participant safety. In order
that this attention is directed toward event safety at all times, a Safety
Steward may not serve in any other official capacity during an event.
In fact, a Safety Steward may not compete in a Solo® event at which
he/she officiates unless another licensed Safety Steward is present to
perform his/her duties while he/she is competing.
Spectator safety at an event means spectator control. If a Solo® event
is run at an approved racing facility, the management of the facility has
probably already addressed spectator control by the use of fencing,
concrete barricades and/or the use of bleachers in protected areas.
It is important that the Divisional Solo® Safety Steward visit the event
site prior to the event to see if any physical barriers or Crowd Control
Marshals are needed and to designate safe spectator viewing areas.
The DSSS, prior to the scheduled event, should make this advance visit
with a representative of the host Region or the event’s chairman so that
ideas and recommendations for spectator control can be implemented.
If an event site is to be used many times during the year, one visit to the
site prior to the first event is usually all that is needed.
NOTE: Spectator Solo® events must also have prior approval pertaining to event safety and such approval and safety requirements are outlined in a letter and/or Insurance Certificate sent to the host region by
the SSC Chairman and SCCA® Risk Management. Information and/
or detailed maps pertaining to spectator, driver, and worker safety requirements for Solo® events can be obtained by contacting the event
chairman. The SSS must implement such requirements prior to and
during the running of the event. However, this does not preclude further
restrictions mandated by the SSS as the need arises.
In viewing an event site prior to or during an event, a Safety Steward
must focus on taking proper precautions (those that would be taken
by reasonable, prudent people) to eliminate danger to spectators from
competing vehicles and to assure driver and worker safety through
proper course design and layout. With the addition of karts to the Solo®
program, special attention should be paid to potential low-lying hazards
adjacent to the course. In viewing all potential spectator areas adjacent
to the course, the Safety Steward should consider the probability of
competing vehicles entering this area due to driver error or mechanical
failure. Consideration should also be given to vehicle component explosions, (i.e., engine, flywheel, and/or clutch) and proper precautions
taken in this regard. If there is a reasonable expectation of spectator
danger, appropriate recommendations for the safety of spectators shall
be made to the Event Chairman or Chief Steward, whichever is applicable.
The Safety Steward’s recommendations may include the placement of
a restraining physical barrier in the spectator problem area, assignment
of Crowd Control Marshals for the area, moving spectators further back
from the course, completely eliminating the area as a spectator viewing location, movement or redesign of the course, or the relocation of
worker stations. Discussions with the Event Chairman or Chief Steward
should include all of these options and a solution should be agreed
upon prior to the start of the event.
Although it should be noted that the Event Chairman or Chief Steward
is as concerned about safety as the Safety Steward, certain aspects of
event safety are the sole responsibility of the SSS. Therefore, a Safety
Steward’s final recommendation(s) for the control of spectators, and
driver or worker safety (relative to course design) becomes mandatory
for the host region. It is the responsibility of the host region to implement safety controls to the satisfaction of the SSS. Failure of a region
to implement these controls can cause the cancellation of the event for
safety reasons, which include loss of insurance coverage as outlined in
the Introductory Section I.4.
A. The Use Of Deputy Solo® Safety Stewards
In order to increase safety control of Solo® Events or for training
purposes, Deputy Safety Stewards may be appointed by the SSS
in charge of the event. They may be trainees (logbook holders) or
licensed Safety Stewards. If trainees are used, proper instructions
shall be given so that the students are familiar with their responsibilities and duties. Remember however, a trainee may not be utilized
as a replacement for a licensed Safety Steward when that Safety
Steward is competing, only a fully licensed Steward may be used in
this situation. When Deputies are used at an event, their license application, or logbook, should be signed-off by the Safety Steward to
indicate the proper performance of the duties assigned.
B. Visiting Solo® Safety Steward
The officiating Solo® Safety Steward is responsible for his/her own
event. A visiting SSS has no authority to alter a decision of the officiating SSS unless that visiting SSS is also the Divisional Solo®
Safety Steward for the Division in which the event is being held, or
is a member of the SCCA® National Solo® Safety Committee. Such
intervention on the part of the DSSS or SSC member should be used
infrequently and only after suggesting altered safety procedures to
the officiating SSS. It should be limited to a situation in which the
DSSS or SSC member identifies a serious safety risk, which he/she
feels, is not being adequately addressed by the officiating SSS.
All visiting Solo® Safety Stewards should make their recommendations known. However, these recommendations shall not be binding
unless issued by one of the parties listed above.
NOTE: It is the responsibility of every SSS to file a report concerning the conduct of an event with the DSSS and the SCCA® National
Office if such conduct is sub-standard to the safety requirements of
the Solo® Rules.
C. Minimum Viewing Distances
A minimum distance of 75 feet from the course edge shall be maintained for all unprotected viewing areas (areas without adequate barrier protection such as concrete walls or highway dividers).
For Spectator Solo® events, minimum viewing distances and viewing area locations have been predetermined by SCCA® after reviewing information submitted by the host region(s). It is the responsibility
of the officiating SSS to obtain this viewing restriction information
prior to the event and implement the stated requirements. However,
the officiating SSS may require additional restriction as the situation
warrants.
In all cases when reviewing potential viewing boundaries, special attention should be paid to the START and FINISH areas, timing truck
and scoreboard areas, and any areas where a competitor is directed
towards people, as well as turns near potential viewing locations.
D. Administrative Details On The Day Of The Event
1. Verify that the SCCA® Insurance Certificate for the event has
been issued and is posted in clear view of all competitors. This
should be done either by visual inspection of the certificate or by
telephone confirmation with SCCA® Risk Management.
2. Review course to ascertain that all reasonable precautions have
been taken with regard to non-participant and participant safety,
that driver safety relative to course design (see Section 2.1) has
been followed and that all worker stations have been located in
safe areas. At Spectator Solo® events, assure compliance with
the Course Inspection/Approval Report.
3. Site boundaries should be designated by permanent barrier
(fence, wall, railing, etc.) and/or a temporary barrier (barricade
tape, streamers, barricades, rope, etc.). Such site designation
would include course area and paddock. Event officials should
control access only to participants.
4. Review event operations with other key event officials.
5. Conduct a meeting with Crowd Control Marshals and/or course
workers prior to start of the event.
6. Make final course inspection just prior to the start of competition
each day, or at resumption of competition when the event has
been stopped for any extended period.
7. The Solo® Safety Steward has the authority to disapprove a site
for karts only when there are upright solid objects (light poles,
fence posts, etc.) on the site within 50 feet of the actual course,
or low-lying objects adjacent to the course area. This does not
include curbs. While safety systems for karts provide acceptable
driver protection for most incidents, upright solid objects and low258 — 2012 SCCA® National Solo® Rules
lying objects present potential hazard for which kart safety systems are not well suited. This rule gives the Solo® Safety Steward
the option of excluding karts without having to declare the site
unsafe for everyone. It is the judgement of the Solo® Safety Steward whether the course design, surface, solid objects, and type of
karts running present an unsafe mix. In most cases, the situation
can be resolved by a course design change.
8. In case of non-compliance with safety requirements, the following
steps shall be taken:
a. Advise the Chief Steward (Solo® Championship events) or
Event Chairman (Solo® regional events) of infraction and request immediate corrective measures is taken before next car
runs.
b. If step a. above has not resulted in corrective action, inform the
Chief Steward or Event Chairman that the event is shut down
until such corrective action is taken.
c. If step b. above is not sufficient, advise the Chief Steward or the
Event Chairman that the insurance and sanction for the event
is SUSPENDED and continued operation of the event is at the
individual’s own risk. All participants shall be notified by whatever means possible. A copy of a memorandum of record (a
hand-written note) shall be given to the Chief Steward or Event
Chairman suspending the event for safety reasons.
d. If step c. above does not result in immediate corrective measures, phone the appropriate persons to cancel the event for
safety reasons. ONCE THIS STEP IS TAKEN, IT IS IRREVERSIBLE.
E. Cancellation Of Event By A Solo® Safety Steward
As noted above, the SSS has the authority to cancel the event for
safety reasons if there is a lack of spectator control and spectator
safety is in jeopardy, if course design does not adhere to Section 2.2,
or if participant safety is in jeopardy. Both SCCA® and its insurance
broker give this authority.
However, every attempt should be made to correct the safety problem before cancellation of the event is contemplated. Insurance/
sanction cancellation is irrevocable and should only be utilized as a
last resort.
If it becomes necessary to cancel an event for safety reasons, the
SCCA® Risk Management emergency weekend telephone number
is 1-800-770-9994.
F. Reporting An Incident
If one of the following incidents occur:
a) Spectator, or participant fatality
b) Serious participant injury (requiring off-site medical treatment)
c) Any spectator injury
Then:
1. Call the SCCA® Risk Management emergency number (1- 800770-9994) immediately!
2. Complete and mail the SCCA® Incident Report Form and original
waiver to SCCA® Risk Management.
3. Complete and mail the postage pre-paid Insurance Claim Form
card to Wells Fargo Insurance, Inc.
4. Within one business day of the event, call the DSSS and report
incident.
If one of the following incidents occurs:
a) Minor participant injury (no medical assistance required)
b) Property damage. (Damage to a competition vehicle is considered
property damage and must be reported to SCCA® Risk Management and the Divisional Solo® Safety Steward)
Then:
1. Complete and mail the SCCA® Incident Report Form to Risk Management and the DSSS.
2. Within one business day of the event, call the DSSS and report
incident.
IX. A FINAL WORD
Since the inception of the SSS program in 1976, a Solo® event has
never been canceled for safety reasons. This is a direct result of the
understanding by the membership of the importance of safety at our
Solo® events.
The cooperation of all event officials toward the goal of having a safe
event has been most evident. However, the past safety record should
never be taken for granted or the safety concerns of SCCA® relaxed —
the potential for injury is always present.
Solo® Safety Stewards, Chief Stewards, Event Chairmen, and host regions have the ability to reduce the possibility of injury and, by so doing,
protect the insurability of all future Solo® events. It is extremely important that this ability be utilized to its maximum extent.
X. GENERAL SUMMARY
PURPOSE:
To enhance the safety of Solo® events by defining the responsibilities, authority, and role of the SSS concerning spectators and participants at all Solo® events.
AUTHORITY:
Authority is per the SCCA® Solo® Rules Introductory Section I.4.
SOLO® SAFETY COMMITTEE (SSC):
This committee administers the program.
LIABILITY OF SOLO® SAFETY STEWARD (SSS):
Each official is protected by being an additional insured under the
SCCA® liability insurance policy. SCCA® will stand by any action or
decision made by a SSS in the course of his or her duties.
REASONABLE ACTION:
A SSS is responsible for taking reasonable action to protect the
safety of participants and non-participants. A SSS will not be held
responsible for any incident or hazard that could not be reasonably
foreseen and protected against.
DEFINITION OF A SPECTATOR:
A spectator is defined as any non-participant or one not signing the
waiver.
DEFINITION OF A PARTICIPANT: DRIVER, CREW, WORKER, OR
GUEST:
A driver, crewmember, worker or guest or any other individual who
has signed the waiver is a “participant.” Participant safety, other than
driver personal safety equipment or vehicle safety is the responsibility of the SSS.
VIEWING DISTANCE:
Except as noted below, the SSS for the event has the authority and
responsibility to initiate and maintain safe viewing distances (75 feet
minimum) from the course. The exceptions to this authority and responsibility regard Spectator Solo® events, which require prior approval by the SSC and SCCA® Risk Management.
OVERLAPPING RESPONSIBILITY:
A SSS is responsible for his or her own event. A SSS visiting other
regional events has no authority or responsibility to alter a decision
of the officiating SSS in attendance unless that visiting SSS is the
Divisional Solo® Safety Steward for the Division in which the event
is being held or a member of the SCCA® National Solo® Safety
Committee.
However, a visiting Safety Steward does have a responsibility to notify SCCA® of any substandard safety related problems.
PLURALITY OF DUTIES:
A SSS may not hold any other positions while administrating the duties of a Safety Steward.
DEPUTY SOLO® SAFETY STEWARD:
A SSS may appoint a deputy or deputies to help in the administration
of his/her duties. SSS license applicants may be used in this capacity for the purposes of training.
CROWD CONTROL MARSHALS:
The Safety Steward’s recommendations may include the placement
of a restraining physical barrier in the spectator problem area, assignment of Crowd Control Marshals for the area, moving spectators
farther back from the course, completely eliminating the area as a
spectator viewing location, movement or redesign of the course, or
the relocation of worker stations. Discussions with the Event Chairman or Chief Steward should include all of these options and a solution should be agreed upon prior to the start of the event.
If Crowd Control Marshals are used, they do not need to be licensed
Solo® Safety Stewards or even Solo® Safety Steward trainees. They
do, however, need to be RESPONSIBLE adults - not minors. Crowd
Control Marshals shall be appointed by and responsible to the designated Event Solo® Safety Steward and shall be briefed about their
responsibilities by that Safety Steward prior to the start of the event.
Crowd Control Marshals, if used, should be on duty during every
heat and should, if possible, wear some type of distinctive clothing
(like bright orange baseball caps, highly visible tee shirts, or reflective mesh vests) to distinguish them from other workers or event
officials.
LOGBOOK:
The Logbook is not required to be submitted to the National Office. It
is available herein for SSS use in tracking events worked.
GENERAL DISCLAIMER OF LIABILITY:
The above Appendix E is not intended to be and shall not be a
warranty or representation that its adoption shall mean that Solo®
events are free from hazards or risks. Solo® events are motorsports
events that involve activities that may be hazardous or dangerous to
both spectators and participants. All such participants and spectators
attend and/or participate in such events at their own risk. Further,
SCCA® can not and does not guarantee that the adoption of this Appendix shall mean that any or all of its requirements will at all times
be enforced or implemented and SCCA® assumes no liability with
regard to such enforcement or implementation or lack thereof.

APPENDIX F - CLARIFICATIONS
Whenever a competitor remains unsure of the legality of certain configurations after studying the rules carefully, he/she is encouraged to
obtain a clarification by writing the Solo® Events Board. The SEB will
attempt to respond as soon as possible. If events require a deadline for
a response, the SEB will attempt to accommodate that deadline.
The requesting member must be aware that clarifications are general
statements of principle offered in good faith and are designed to clarify
intent, but they do not afford specific cars permanent protection from
subsequent protest and disqualification. Nor are the responses from the
SEB inviolable instructions to protest committees. This is because in
most cases the SEB is responding to a specific or limited question and
operating only on information supplied by the interested party which
cannot be guaranteed by the SEB to be complete. Photos and descriptions provided for the SEB’s consideration may not be clear or may not
portray the information in the full light of issues of information that may
subsequently be considered by a protesting party. Due to the volume of
mail, the SEB cannot research each item for the competitor. Even if it
could, it could not assure that new information would not be forthcoming
at a future date.
The rules are constantly evolving as the pressures of competition induce
competitors to exploit each and every facet of the rules. Such competitors may discover and act in good faith on an entirely new interpretation
that the SEB feels compelled to pronounce compliant according to the
letter of the rules but in fact circumvents the rulesmakers’ original intent
and may result in a long-term disservice to the majority of competitors
if allowed to stand. In these cases the SEB will revise the rule but only
after going through the required rules change process. Therefore it is
always in the competitor’s best interest to obtain a clarification before
investing large amounts of time, money and effort in an interpretation
which may be shortlived. Such rulings will be accompanied by the appropriate caveats that the SEB is considering such a change.
In the extreme, some competitors feel the need to base their efforts
largely on clever re-interpretations of rules rather than driving prowess
or engineering skill based on common principles offered in good faith
by the SEB and accepted by the majority at face value. Such efforts are
constantly challenging the SEB and those who pursue this route must
accept the risks they take when they exploit loopholes that clearly are
not in the best interest of the membership at large. In such cases, the
interests of the majority must ultimately hold sway over “fairness” to the
individual.
VEHICLE IDENTIFICATION
The illustrations are intended as examples to help guide competitors in
the placement and sizing of their numbers and class letters.
TIMING AND SCORING PROCEDURES
The Official Times, which include copies of the Master Time Log with
penalties included and the Course Incident Reports, will be posted after
each run. If a computer malfunction occurs and a printout cannot be
posted, this will not delay the start of the next runs; however, every effort will be made to have a computer printout of preliminary results after
each run.
The Course Incident Report sheets will be picked up halfway through
each run from each corner station and posted as part of the Official
Results. These supersede the penalty portion of the Master Time Log if
there is a discrepancy in cone counts or DNFs. The reason for picking
up the Course Incident Report sheets halfway through each run is so
that the competitors who run in the beginning of the heat will be able to
see the times and cone counts before their next run.
Theoretically, downtime should only occur when the corner sheets are
being picked up (approximately two minutes).
It is the competitor’s responsibility to bring any posting discrepancies to
the attention of the Chief of Course, who will then confer with the Chief
of Timing. This can be done without having to go through the Protest
procedures; however, if a competitor feels that he/she has not received
a satisfactory action or reply from the Chief of Course, the next step is
to go through the Protest procedure.
Appendix F - Clarifications — 265
GENERAL
A Scott Russell linkage is a locating device similar to a panhard rod or
a Watts linkage, which generally accompanies a solid axle rear suspension.
STOCK CATEGORY CLARIFICATIONS
AIR CONDITIONING
Stock class cars with optional air conditioning are allowed to compete
without the belt in place. Additionally, the entire air conditioning system may be removed, but any related components (springs, radiator,
etc.) that are part of an air conditioning package must be returned
to standard parts for the standard model (non-air conditioned). Removal of part of the air conditioning system is allowed only if no other
components for the car differ between model’s equipped with and
without air conditioning (i.e., springs, radiator, etc).
Air conditioning may be added to any car as a “comfort and convenience” item, provided it serves no other purpose and other components are not added or deleted unless otherwise authorized by the
current Solo® Rules. If a factory option, may be removed and backdated as an assembly or separate components of the system may be
removed (i.e., individual under-hood components only).
AIR FILTER ELEMENT
The engine air filter element may be removed or replaced provided
the air flow path remains as originally designed (i.e., no additioinal
openings). No other components of the air induction system may be
removed, replaced, or modified.
CHEVROLET CORVETTE SPARE TIRE COVER
The spare tire cover on a Corvette (C4 chassis) may be removed
when the spare tire is removed as allowed by section 13.2.G.
COIL SPRING PERCHES
The intent of the Stock Category allowance for alternate shock absorbers is that the dimensional characteristics of the shock absorber
and spring location must remain consistent with those of the original units, as per section 13.5.F. In the case of coil spring perches
on aftermarket shocks, the vertical distance of the spring position
above the lower shock mounting point must be no less than the distance found on the original equipment unit. If the characteristics of
the shock (e.g., gas pressure) are such that this positioning results in
a change in the car’s ride height, that change is permitted.
CONTROL ARM SPACERS - CHEVROLET CORVETTE (1984+)
The spacers located on the fasteners for the front upper control arms
may not be removed or modified to gain additional camber/caster.
Only the shims may be removed.
ENGINE MODIFICATIONS
Allowed engine modifications in the Stock and Street Prepared category:
The clarifications below reflect the basic premise of all the Solo®
preparation rules that only modifications specifically designated by
the rules are allowed.
a. Heads and/or blocks may only be trued (shaved) to the service limit
specified in the factory workshop manual. If a service limit is not
specified, then the head and/or block may not be trued (shaved)
and must be used at the specified original dimension.
b. Camshafts are not considered normally expendable items, therefore they must not only meet original specifications but they must
be from the original manufacturer. Aftermarket units are not allowed.
FACTORY RECALLS
Factory recalls fall under the requirements of section 13.0, which
states “…Stock category cars must be run as specified by the factory...” Recalls designated by the factory as being installed only in
response to complaints are considered optional and allow for both
specifications (pre- and post-recall) to be valid. However, if the manufacturer issues a mandatory recall, only the most current specification is valid. The U.S. government provides recall information via
telephone.
GM ECU REFLASH
The Technical Service Bulletin #06-06-04-051 regarding engine recalibration (i.e., an ECU reflash) of the Z0K Solstice and Cobalt SS
is not legal for Stock category use since it is specified for competition
purposes and thus does not meet the requirements of sections 13.0,
12.4, and 3.8.A.
GM STEERING KNUCKLES
The competition-only steering knuckles for the Cobalt, G5, and ION,
as specified in Service Information Document #1864485, do not
meet the requirements of the Stock category.
HARNESS BAR
A harness bar which attaches only between the upper seat belt
mounts on the B pillars complies with section 13.2.I provided the
constraints of 13.2.I are met.
HEADLIGHTS
Retractable headlights may only be positioned in configurations intended by the manufacturer. This means that a partially-up position
is only permitted if it can be attained via a designed intermediate
position of the switch used to raise and lower the headlight pods.
HYUNDAI GENESIS R-SPEC ALIGNMENT BOLTS
Section 13.8.E allows for camber bolts offered by the manufacturer
for a specific model and year. These bolts meet the rule and are
compliant for use in Stock Category.
INTERCOOLERS
Intercoolers may not be packed with any type of ice during runs.
LOTUS ELISE SPORT PACK
The Lotus Sport Suspension (currently known as the Sport Pack) is a
factory option package for the Lotus Elise which is eligible for Stock
category competition. It should not be confused with the 2006 Lotus
Sport Elise, which is a limited-production model (50 cars) developed
by Lotus Sport (a division of Lotus Cars which develops high performance upgrade components for Lotus vehicles).
LOTUS ELISE WHEEL SENSOR SHIMS
The wheel speed/cruise control sensor “shims” on a Lotus Elise are
considered a dual-purpose item, since they also affect available
camber range and may not be removed.
MAZDA MIATA ANTI-ROLL BAR MOUNTS
For the purposes of section 13.7, the upper (flat) and lower (Ushaped) mounting brackets for the front anti-roll bar on a Miata are
both considered to be anti-roll bar brackets.
MAZDA MIATA BUMP STOP/DUST BOOT
On a Mazda Miata with an integral bump stop/dust boot configuration,
the OE boot may be detached from the OE bump stop and removed,
replaced, or modified under the allowances of section 13.5.D.
MAZDA MIATA OPTION CONVERSIONS
Only the year model 2007 Miata may be converted to the 2007 MS-R
package.
MINI COOPER JACKING PUCKS
The four black jacking pucks underneath Mini Coopers may be removed before competition for safety reasons. These are considered
somewhat similar to a wheel center cap in the type of hazard they
can present if they come off the car at speed during competition.
PORSCHE STRUT ORIENTATION
The strut on a Porsche 911 GT3 (996/997) may not be rotated from
its OE orientation since this configuration is authorized by the manufacturer for “racing” (i.e., competition) purposes only and thus does
not meet the requirements of Section 13.
PUSH ROD GUIDE PLATES
Push rod guide plates are only allowed in Stock or Street Prepared
when installed as original equipment by the vehicle manufacturer or
when the factory service manual allows push rod guide plates as an
acceptable repair method.
SEAT PADDING (applies to Solo® only)
Cushions may be used for the purpose of bringing the driver within
reach of the controls of a vehicle. The word “cushion” means a freestanding pillow, towel, blanket, or similar article consisting of foam
rubber, feathers, or comparable materials. Such cushions may not
be attached either to the vehicle or to the driver’s body. Prohibited
means of attachment include, but are not limited to the following:
straps, hooks, snaps, loop-type fasteners (e.g., Velcro), adhesives,
or similar aids. The intent of this allowance is to enable the driver to
more comfortably operate the controls of the vehicle without enhancing the driver seat’s ability to hold the driver in place.
SHOCK ABSORBERS
Section 13.5.D does not apply to the following aspect of this configuration: The hole in the metal and rubber shock absorber bushing
found at the top of the shock absorber in the suspension of a Mazda
Miata may be enlarged to accommodate the diameter of the shaft of
a replacement shock absorber.
SHOCK BUSHINGS
For E36 and E46 BMW’s, 13.5.B permits the removal of the shock
bushing from the rear shock upper mounting plate (e.g., drilling, cutting, burning out the bushing) and replacing it with another bushing.
This also includes shock bushings located in control arms, etc. This
does not allow other modifications to the plate itself or use of an
alternate plate.
SPARE TIRE COVERS
A spare tire cover which can be secured in place by original fasteners, such as bolts, nuts, snaps, straps, etc., is not normally considered a “loose item” and thus is not removable under the provisions
of safety inspection requirements. Covers which cannot be secured
by such means may be removed. A cover which is secured to the
spare itself, and thus becomes a loose object when the spare tire is
removed as allowed by section 13.2.F, may be removed with the tire.
Competitors who are in doubt as to whether such a tire cover is correctly viewed as a loose item are advised to leave it in place.
SUSPENSION ADJUSTMENT
The Stock category suspension adjustment allowances do not allow non-factory-authorized use of eccentric or smaller bolts. Factory
authorized crash repair methods may only be applied to the extent
needed to restore the suspension to within it specified range of adjustment. The crash repair methods referred to would include such
methods as frame, unibody or suspension component straightening
(bending) or unlimited grinding of attachment holes.
Section 13.8 does allow the use of factory authorize methods of
adjustment for non-competitive use which have a specific, physical
limit. Examples would include the alternate size bolts authorized by
VW for the Golf and the grinding of strut mounting holes to a specific
dimension authorized by GM for J-cars. Any alignment specifications
resulting from these authorized methods are allowed.
SUBARU IMPREZA WRX OPTIONS
The following port-installed options on the Subaru Impreza WRX,
are listed when installed on the vehicle’s window sticker and pending
evidence to the contrary are considered compliant: carbon fiber trim,
turbo boost gauge, titanium shift knob, short throw shifter, rear diff
protector, spoilers, and arm rest extension.
“THIRD SPRING” SHOCK ABSORBERS
The Penske “Hydraulic Third Spring” shock absorber configurations,
and any others like them, are not allowed by the Stock category rules.
WELDING AND OPTION PACKAGE CONVERSION
Option package changes which require welding to be accomplished
are allowed provided they comply with the rule requiring that the
option package conversion be complete and supported by factory
documentation.
STREET TOURING CATEGORY CLARIFICATIONS
BMW 3-SERIES LISTINGS
For the purposes of 14.2.F.1, all BMW 3-series generations (E30,
E36, E46, etc.) are considered the same model, including “M” versions.
BODYWORK/INTAKE
Section 14.10.B specifically allows the modification of air intake tract
system components up to the engine inlet as defined therein. The
same rule specifically prohibits modifying the existing structure of the
car to accommodate the allowed intake tract system modifications.
The factory partitions surrounding the MINI Cooper and MINI Cooper
S air filter housing are considered to be separate vehicle structures
not integral to the air intake tract system. Therefore, it is not permitted to modify these partition structures. These structures must be
maintained in the original OE configuration. This is in keeping with
previous rulings on this same subject for other vehicles.
BMW X-BRACE
Cross reinforcement (X-brace) from 1995 BMW M3 (E36) Lightweight and Convertible is not complaint for the M3 coupe. Cross
reinforcement was not available from the factory on eligible coupe
models, nor does it qualify as a standard part (see section 12.4) via
parts manual supercession, thus making it non-compliant for both
Street Touring and Stock category usage.
MAZDA MIATA MOTOR MOUNTS
All three pieces of a Miata motor mount (Engine Mount Rubber,
Stopper Casing and Engine Bracket) are considered to be part of the
“Engine Mount” in 14.10.J and 15.10.J.
SEAT BELT RECEIVERS
Seat belt receivers integral to stock seats do not have an allowance
for deletion and must be maintained if replacement seats are installed.
STEERING WHEEL
Steering wheel hub spacers and adapters are considered part of the
steering wheel and are allowed to be substituted with the steering
wheel per section 14.2. The resulting change in steering wheel position is permitted.
SUBARU WRX HEAT SHIELD
For the 2002-2007 Subaru WRX, the heat shield attached to both the
turbo and downpipe is an exhaust heat shield and is therefore subject to “minimal modification” allowed in 14.10.D, but not removal.
STREET PREPARED CATEGORY CLARIFICATIONS
AIR BAG, PASSENGER
Section 15.1.C does not permit the removal of a passenger-side airbag from the dash of an airbag-equipped Miata. The entire dashboard may be backdated to one which did not have an airbag, provided the requirements of 15.1 are met.
BUMPER UNITS
The allowances of 15.2.I do not currently permit a replacement nonstandard front bumper/spoiler integral front fascia unit.
ENGINE MODIFICATIONS
Allowed engine modifications in the Stock and Street Prepared category:
The clarifications below reflect the basic premise of all the Solo preparation rules that only modifications specifically designated by the
rules are allowed.
a. Heads and/or blocks may only be trued (shaved) to the service limit
specified in the factory workshop manual. If a service limit is not
specified, then the head and/or block may not be trued (shaved)
and must be used at the specified original dimension.
b. Camshafts are not considered normally expendable items, therefore they must not only meet original specifications but they must
be from the original manufacturer. Aftermarket units are not allowed.
FERRARI CLASSIFICATION
The Ferrari F430 Scuderia is covered as an option package by the
existing F430 listing in ASP.
IGNITION SYSTEM, CRANK FIRE
SR, Section 15.9.A. For the purposes of triggering a crank fire ignition system, which is an allowed modification in the Street Prepared
category, a trigger ring may be added to the crankshaft, or a crankshaft pulley may be modified to serve the purpose of the trigger ring.
Mounting of the trigger ring, or modification to the crankshaft pulley
may serve no purpose other than to provide a means of triggering
the ignition system. The original distributor may be removed and the
distributor mounting hole covered with a plate. The location of electronic ignition control modules is unrestricted.
LUBRICATION SYSTEM, ROTARY ENGINE
Any rotary engine model vehicle that has a lubrication system that
incorporates an oil line injecting oil into the fuel system in the stock
configuration must maintain that arrangement in Street Prepared,
even if an alternate carburetor is used.
MAZDA MIATA AIR CLEANER KIT / PLASTIC SHROUD
On the MX-5 Miata (NC), a plastic shroud (PN 56-181L) interferes
with the routing of a “cold air kit” tube which facilitates air cleaner
relocation; the plastic shroud is not an “air cleaner,” nor is it part of
the “intake system.” Mazda calls this piece a “PLATE, SEAL-RAD.
SHROUD.” Mazda does not include it within the air-intake system
in their factory documentation. It may well divert airflow in a manner which affects the stock airbox/air horn, but so does the bumper,
radiator, etc. This piece may not be removed or modified to facilitate
the installation of an intake kit.
MAZDA MIATA HARDTOP/SOFT TOP
Per 15.1, the Miata covered by the listing in CSP may update/backdate to the hardtop/soft top specifications of the Club Sport package,
which permit the car to compete with the hardtop on, and/or with the
soft top on, or with both removed.
MAZDA MIATA MOTOR MOUNTS
All three pieces of a Miata motor mount (Engine Mount Rubber,
Stopper Casing and Engine Bracket) are considered to be part of the
“Engine Mount” in 14.10.J and 15.10.J.
PUSH ROD GUIDE PLATES
Push rod guide plates are only allowed in Stock or Street Prepared
when installed as original equipment by the vehicle manufacturer or
when the factory service manual allows push rod guide plates as an
acceptable repair method.
REAR VIEW MIRROR
The Street Prepared rules do not permit the removal of rear view
mirrors.
SPRINGS, LEAF
Per Section 15.8.A, for vehicles originally equipped with leaf springs,
either multi- or mono-leaf springs may be substituted.
SPOILERS
The Street Prepared rear spoiler allowance was intended to allow common aftermarket body kits and spoilers that have no notable aerodynamic effect at autocross speeds. Solo® Rules section
15.2.H.2.b states that, “The spoiler may not function as a wing.” For
purposes of rulemaking and interpretation, a “wing” has been generally understood to mean an aerodynamic device making use of air
passing both over and under a solid element to create aerodynamic
force. A rear “spoiler” is generally understood to be an aerodynamic
device fixed to the rear bodywork of the vehicle where air passes
over, but not under, the solid element to create aerodynamic force.
The base of a “spoiler” is contiguously attached to the bodywork
(e.g., deck lid) of the vehicle to prevent airflow underneath the spoiler
element.
Some cars are equipped by the OEM with standard or optional bodywork elements that meet the definition of “wing” stated above, although they may be identified in marketing material, owner’s manuals, shop manuals, and/or parts lists as “spoilers.” These bodywork
elements may not be modified per 15.2.H.2.b, except to be replaced
with either a standard or optional OE element, or exact replica of
a standard or optional OE element in an alternate material, as per
15.2.H.2.a. “Plugging” the underside opening of an OE wing by any
means, including but not limited to tape, cardboard, foam, etc. to turn
it into a spoiler and allow additional spoiler additions is not a compliant modification. Examples of cars having such OE bodywork elements that would be considered wings by definition include, but are
not limited to, the 1993+ Chevrolet Camaro, the Subaru Imppreza
WRX STI, numerous Ford Mustang variations from 1987 on, Dodge
SRT-4, and Mitsubishi Lancer Evolution.
NOTE: 15.1.C is not affected by this clarification.
SUBARU IMPREZA SUBFRAME BOLTS
Subframe lock-down bolts (AKA Botox Bolts) are not compliant for
use in Street Prepared. Section 15.2.D only allows for replacement
of subframe bushings and does not provide any allowance for additional fastening hardware.
SUNROOF
A non-OE sunroof replacement panel may not be used in place of
the OE sunroof.
TORQUE ARMS
The longitudinal member which GM refers to as as “torque arm” on
3rd and 4th generation Camaros, which controls differential movement, is covered by the allowances of 15.8.E and may be substituted
or modified.
STREET MODIFIED CATEGORY CLARIFICATIONS
FIAT / YUGO PARTS
Fiat and Yugo components may be mixed as permitted under Section 16.1.
PORSCHE FASCIA
With regard to a Porsche 911, the fascia is the painted plastic part
and was not present on earlier years of the model. The attachment
points behind the fascia may only be modified per 16.1.O to permit
installation of an allowed alternate fascia. An early 911 may only use
a substitute fascia if the car can be legally updated per 15.1.C (Street
Prepared) to a later bumper configuration employing a fascia.
PREPARED CATEGORY CLARIFICATIONS
CORVETTE CROSS MEMBER
The BP supplemental class rules do not permit the removal of a Corvette C3 cross member and replacement of it with one from a C4 or
C5 without incurring a weight penalty.
MODIFIED CATEGORY CLARIFICATIONS
ARIEL AND TONIQ
The Ariel Atom and Toniq may be eligible for BM or AM, if the car is
in compliance with the class rule set.
BODYWORK
Pursuant to retaining consistency with the intent of Club Racing regulations, the SEB is concerned about modifications to bodywork for
the purpose of enhancing downforce. CM Formula Ford competitors
wishing to make body alterations to their cars should request a ruling
on the desired configuration if there is any doubt as to its legality.
CLUB RACING ASR VEHICLES
Vehicles prepared to the “new” Club Racing A Sports Racer (ASR)
specifications defined in GCR/SRCS A.1.b are eligible to compete
in AM. Vehicles prepared to the “old” ASR specifications defined in
GCR/SRCS A.1.a remain eligible for BM.
CRASH STRUCTURES
Club Racing GCR section 9.4.5.F., regarding deformable crash
structure in formula cars, does not apply in Solo®.
DM AND EM AERODYNAMICS
Section 18.1.E.3 Front Aero, as it applies to the case of the Lotus
Seven and similar cars with irregular front top view profiles, for front
spoiler/splitter construction: As an example, the Lotus Seven has a
narrow central nosecone and separated front fenders. If a front spoiler wider than the nosecone were added, it would hang in free air. Air
would flow both above and below the spoiler, meeting the definition
of a wing, which would be an illegal configuration. However, the rules
allow the front spoiler to be as wide as the rear bodywork of the car
at axle height. A front spoiler/splitter only as wide as the nosecone
would be of limited aerodynamic value. Furthermore, front aero is
needed to balance rear aero; limiting one effectively limits the other.
So, in the interest of parity, the Seven and similar cars are allowed to
add a full width front spoiler. However, if the builder would add such
a spoiler, he/she must fill in the front bodywork, closing the gaps
between the nosecone, spoiler, and clamshell fenders, to avoid creating a “wing.” This will require adding bodywork filler panels for the
car, and will change its look as it changes its function. The temptation might be to further optimize the cars front end for aero purposes,
creating a sports racer-like wedge-shaped front using angled ramps
to join the fenders to the spoiler/splitter assembly. This would exceed
the parity intended by this allowance and is not allowed. Therefore,
when a Lotus Seven or similar vehicle uses a full-width front spoiler,
the car’s spoiler/ air dam is required to be vertical (between 80-100°)
for the lower 8” of its extent.
The splitter is to be horizontal within +/- 3/16” over its length. Outside
of these constraints, the builder may close off the front of the car in
any manner necessary. The change in top view outline caused by
these bodywork changes is allowed. The spoiler/air dam cannot be
any wider than the rear bodywork at axle height. Splitters can extend
6” forward of the top view outline, but cannot extend wider than the
top view outline.
DM AND EM PROGRESSION
The CP-GP Prepared Category rules are the foundation for the
preparation of a Modified Category DM or EM vehicle. The Modified rules are a specified progression from Prepared Category and
are intended to be far less restrictive than the Prepared rules. Examples of areas where CP-GP rules are not intended to be restrictive
in Modified are as follows: engine and drivetrain, wheelbase, track,
and brake location.
The CP-GP rules are to be followed when they do not conflict with
specific allowances or the intent of the Modified Category rules. This
clarification is to eliminate questions about the actual relationship
between the two categories, and to indicate the intent of that relationship.
Inclusive of that intent, if it doesn’t say you can, then you can’t.
FORMULA FORD BODYWORK RESTRICTIONS
Members who have questions concerning the legality of a particular
car’s configuration should submit detailed photographs and/or drawings of the car to the SEB (Solo Events Board) in order to determine
if the specific bodywork of concern is considered compliant for CM.
FORMULA 440
FM class is for current year Club Racing GCR-compliant cars except
as amended by the Solo® Rules. The current GCR (Formula Car
Specifications) requires that F440 be constructed with the driver’s
feet behind the front edge of the front wheels. Short wheelbase cars
constructed prior to this change are “grandfathered” and remain compliant even though the driver’s feet extend beyond the front wheels.
FORMULA 500 EXHAUST
Solo® Rules section 3.5, “Mufflers”, overrides the F500 sound level
limit in the Club Racing GCR (Formula Car Specifications), but not
the exhaust length limit.
MOTORCYCLE-ENGINED PRODUCTION-BASED CARS
Relative to an otherwise compliant DM/EM but motorcycle-engined
vehicle running in BM, it is the intent of the rules allowing such class
entry to permit the competitor to have two preparation options: the
car may be prepared to the appropriate Club Racing GCR/SRCS, or
it may continue to adhere to the DM/EM Solo® specifications.
However, in either case, the applicable displacement/minimum
weight shall be as listed in the Solo® BM rules. There shall be no
mixing of the two rule set allowances. EXAMPLE: Motorcycle-engined DM/EM cars in BM may not utilize any Sports Racer aerodynamic allowances without being mandated to fully prepare to all
Solo® Rules requirements.
SOLO® VEE / FORMULA VEE
The Solo® Vee and Formula Vee at Solo® events are not required to
comply with the section of the Club Racing GCR Formula Car Specifications, C.8 requiring additional panels to prevent the intrusion
of objects into the driver area. All other requirements of the Solo®
Rules, 18.3 Formula Cars, Appendix A, and the 1993 Formula Car
Specifications are in effect.
KART CLARIFICATIONS
BRIGGS AND STRATTON ENGINE
The Briggs & Stratton World Formula engine as homologated by CIK
is eligible for competition in JA and JB.
EASY KART
KM: The EasyKart is considered legal for KM provided its construction meets the requirements of Section 19, particularly 19.1.D.2
WORLD FORMULA CHAIN / SPROCKET / GEAR
It is permissible to use an alternate chain/sprocket/gear (type 35) on
the World Formula engine as used in the FJ classes.
APPENDIX G - KARTS AT SOLO® EVENTS
I. APPROVAL PROCEDURE
A. Regions conducting Solo® events which will have karts competing must so indicate on the sanction application.
B. A post event report describing the kart portion of the event should
be submitted, but not required, with the usual Audit Report Form.
These event reports will be helpful to the SCCA® in more effectively evaluating the kart program.
II. EVENT OPERATION PROCEDURES
A. 125cc shifter karts (KM) are the fastest karts allowed.
B. Karts will not be allowed to be driven under power through the
paddock; they must be pushed, either on the ground or on a portable stand.
C. A grid area must be established that is either separated from the
regular car grid or grids karts with similar sized vehicles such as
formula cars. Traffic flow to and from the grid area must be controlled.
D. If karts are allowed which require a push-start, such as shifter
karts, the grid area must accommodate this need adequately.
E. All karts will be run as a group or grouped with formula cars, and
not intermixed on course with full-bodied cars. However, at the
discretion of the Solo® Safety Steward, the Event Chairman, and
the Chief Stewards, karts may be allowed on course with full-bodied cars if the course design allows for safe separation, such as
the start and finish areas being remote from each other.
F. Event procedures regarding karts will be announced at the drivers’
meeting and will also be in written form for posting.
Appendix G - Karts at Solo® Events — 277
APPENDIX H - JUNIOR DRIVER PROGRAM
I. RULES AND PROCEDURAL UPDATES
As this program remains in the developmental phase, rule updates
or clarifications may appear periodically in the Fastrack® section of
the official SCCA® publication or www.scca.com.
II. EVENT OPERATION
A. All procedures described in Appendix G, Section II and in Section
19.2 would apply. The Junior Driver Program may either be run
incorporated into an event, run concurrently on a separate course,
run after an event, or as a stand-alone event.
B. In addition to the above, the following procedures would apply:
1. Appointment of at least one Youth Steward. Two additional
assistant Youth Stewards are recommended. Duties are described below.
2. Conduct an additional driver’s meeting for the Junior Drivers.
3. Provide a small area for Junior Driver vehicle orientation.
4. Develop work assignments for Junior Drivers that are appropriate to their individual ages and background. An alternate to a
traditional work assignment could be a safety training session.
Either work assignments or training sessions will be under the
supervision of the Youth Stewards.
NOTE: Waiver duty is limited to persons above the age of majority of the state in which the event is held, however, Junior
Drivers may assist an adult.
C. Youth Steward Duties
The Youth Steward is a licensed position and must be an SCCA®
member in good standing. License applications are available via
the SCCA® website (www.scca.com). Duties are as follows:
1. In conjunction with the event chairperson and event Solo®
Safety Steward, establish specific event procedures relative
to schedule, grid and site layout, special instructions, Junior
Driver vehicle orientation, etc.
2. Oversee the conduct of all Junior Drivers with the authority for
disciplinary action including reprimand, time penalty, disqualification, expulsion from the site, and driver suspension.
3. Conduct a Junior Drivers’ meeting that emphasizes safety, responsibility and event procedures.
4. Conduct a Junior Driver vehicle orientation session prior to
competition runs for inexperienced drivers.
5. Lead at least two mandatory course walks for inexperienced
Junior Drivers.
D. Pilot Program for Younger Drivers
Selected Regions will be allowed to have drivers 5 years old and
older participating on Solo® courses using Cadet carts with 3HP
engines, as per WKF rules. The Solo® course used could either
be the regular event course during or after the event, or a totally
separate course. Regions may only be approved for this pilot program if they have been running a Solo® Formula Junior program
for a minimum of one year, with at least four events conducted
with Junior Drivers. The SCCA®National Office will issue the approvals to the Regions for participation in this program.
III. JUNIOR DRIVER ELIGIBILITY
A. SCCA® member.
B. For classing purposes, the minimum age is 8 years old (see below). It is important that Solo® Rules Section 1.3.2.O be strictly
adhered to when Junior Drivers are participating. Formula Junior
B (JB) drivers must be 8 years old before being allowed to compete. Formula Junior A (JA) drivers must be between 12 years old
and 18 years old. Regions are free to adjust the JB to JA transition
age (the year in which a child turns 12 years old) to accommodate
their Region’s competition season.
For sanctioning requirements the minimum age is 12 years old.
However, the minimum age may be reduced to 8 years old for any
SCCA® Region which requests and is approved for an exception.
Approval may be granted only after the Region submits the name
of its Youth Steward and a written description of how the Junior
Drivers will be administered. Additionally, the Youth Steward will
be required to contact the Youth Steward in an experienced pilot
program Region to learn of their experiences and methods.
C. Completed minor competitor waiver.
D. Attendance at Junior Driver meeting and course walk.
Appendix H - Junior Driver Program — 279
APPENDIX I - SOUND MEASUREMENT PROCEDURES
The provisions of this section are recommended, but not presently required. The specific DB levels (values of “XX”) are expected to be assigned by Regions according to the needs of their sites.
The competitor shall carry sole responsibility for ensuring their vehicle
complies with these Sound Control Standards and Procedures. Vehicle
sound emission is not a constant factor that can be trimmed to barely
legal (in the manner of engine displacement or vehicle weight.) Sound
emissions may vary significantly from morning to afternoon, and day to
day, so the competitor is advised to target any vehicle sound emission
level “adjustments” to well under the limit, to allow for variations in conditions. The intent of the following rules is to truly make our events quieter by limiting the sound level produced by individual vehicles. Competitors are expected to use mufflers as the primary method for sound
reduction. Sound measuring stations will be on both sides of vehicles to
ensure sound output levels are below limits.
STANDARD
Maximum limit of (XX) dB, A weighted, at the measuring point.
MEASUREMENT
The measuring point will be established during course set up, and approved by the event chair. The course map shall be provided to the
chief of sound two days before the event.
When possible, measurements will be taken at all event sites to provide
information for competitors.
Measurement will be taken at a point on course where the car can
reasonably be expected to be at full throttle, under load, and at high
RPM.
The measuring point will be 50 ft from the edge of the course lane, using a coned gate as a reference. More than one measuring point may
be established.
SOUND STATION(S)
A Sound Station will be established at the measuring point(s) on the
course. At a minimum, an ANSI Type 2 sound with a digital readout will
be used.
The microphone will be mounted on a tripod, 3 to 4 feet above ground
level.
The microphone will be positioned perpendicular to the vehicle’s direction of travel.
The meter will be set to “A” weighting, “Slow” Response.
When possible and practical, the Sound Station(s) will be as far away
as practical from inhabited buildings.
The Sound Station Operator will record the Heat #, Run #, Car # and
Class and Sound Reading on a Log developed for that purpose.
Sound Logs will be posted on site after each run group, and on the web
following the event.
Sound Logs will be maintained for one year.
Every car will be measured on every run.
The Sound Station Operator and the Grid Sound Control worker will be
equipped with a radio on the same channel as the Corners, Grid and
Control.
One or more (as required) of the “downstream” corner stations will be
equipped with a black flag and dedicated flagger.
The Sound Control Grid worker will be equipped with a clip board and
notepad to record the car number of violators announced by the sound
operator, for his reference when the car returns to Grid.
VIOLATIONS
When a vehicle exceeds (XX – 3) dBA, the sound operator will inform
the grid sound control worker.
When a vehicle exceeds (XX + 3) dBA, the sound operator will announce
over the radio, “sound flag, sound flag,” then state the car number and
class, and the measured reading. The Grid Sound Control Worker will
record the car number and sound reading.
The corner station(s) with the black flag will display it when called by
Sound Control, so it can be seen by the driver, signifying to the driver
that his vehicle has exceeded the (XX + 3) dBA secondary limit.
The driver must immediately come off the throttle and continue through
the course, without either stopping or driving at a competition pace.
Any run (XX) dBA or over will be scored a DNF.
The driver will be notified of any measurement over (XX – 3) dBA.
When a car in violation ((XX) dBA or over) returns to grid, the Grid
Sound Control worker will notify the driver of the car’s measured sound
level. The driver will be given the opportunity for a “mechanical delay”
to attempt to reduce the vehicle’s sound level. If, in the judgment of the
Grid Sound Control worker, the driver has attempted a viable remedy,
he will authorize a “second chance run”. If the driver(s) declines any
“repair” action, or the “repair” is deemed inadequate or inappropriate
by the Grid Sound Control Worker, the driver(s) will forfeit all subsequent runs in that vehicle. The Grid Sound Control Worker may offer
advice to competitors. This advice, however, shall be in no manner be
construed to imply that said suggested corrective action(s) absolves
the competitor from complying. If the vehicle exceeds either limit on
the “second” chance run, the vehicle may be given one “final chance”
run if the vehicle meets all the requirements of the previous paragraph
(second chance run).
If the vehicle exceeds the limit on the “final” chance run, all subsequent
runs by that vehicle, if any, are forfeited.
Appendix I - Sound Measurement Procedures — 281
Drivers may appeal the decision of the Grid Sound Control Worker to
the Event Chair.
